APPLICATIONS
The devices have an ⅛ unit load receiver input impedance,
which allows up to 256 transceivers on a bus. Because only one
driver should be enabled at any time, the output of a disabled or
powered-down driver is tristated to avoid overloading the bus.

GENERAL DESCRIPTION
The ADM3070E to ADM3078E are 3.3 V, low power data
transceivers with ±15 kV ESD protection suitable for full- and
half-duplex communication on multipoint bus transmission
lines. They are designed for balanced data transmission, and they
comply with TIA/EIA standards RS-485 and RS-422.

Figure 3.
The receiver inputs have a true fail-safe feature, which
eliminates the need for external bias resistors and ensures a
logic high output level when the inputs are open or shorted.
This guarantees that the receiver outputs are in a known state
before communication begins and when communication ceases.

GENERAL DESCRIPTION
(continued from Page 1)
The driver outputs of the 250 kbps and 500 kbps devices are
slew rate limited, in order to reduce EMI and data errors caused
by reflections from improperly terminated buses. Excessive
power dissipation caused by bus contention or by output
shorting is prevented with a thermal shutdown circuit.
The parts are fully specified over the industrial temperature ranges and are available in 8-lead and 14-lead
narrow SOIC packages.

Description
Receiver Output. When enabled, if (A − B) ≥ −50 mV, RO is high. If
(A − B) ≤ −200 mV, RO is low.
Receiver Output Enable. A low level enables the receiver output.
A high level places it in a high impedance state. If RE is high and DE
is low, the device enters a low power shutdown mode.
Driver Output Enable. A high level enables the driver differential
A and B outputs. A low level places it in a high impedance state. If
RE is high and DE is low, the device enters a low power shutdown mode.
Driver Input. With a half-duplex part when the driver is enabled, a
logic low on DI forces A low and B high; a logic high on DI forces
A high and B low. With a full-duplex part when the driver is enabled,
a logic low on DI forces Y low and Z high; a logic high on DI forces
Y high and Z low.
Ground.

CIRCUIT DESCRIPTION
The ADM307xE series are high speed transceivers for RS­485
and RS-422 communications. Each device contains one driver
and one receiver. All devices feature fail-safe circuitry, which
guarantees a logic high receiver output when the receiver inputs
are open or shorted or when they are connected to a terminated
transmission line with all drivers disabled (see the Receiver FailSafe section). The ADM307xE also feature a hot-swap capability, allowing line insertion without erroneous data transfer
(see the Hot-Swap Capability section). The ADM3070E/
ADM3071E/ADM3072E feature reduced slew rate drivers that
minimize EMI and reduce reflections caused by improperly
terminated cables, allowing for error-free data transmission at
rates up to 250 kbps.
The ADM3073E/ADM3074E/ADM3075E also offer slew rate
limits, allowing transmit speeds up to 500 kbps. The ADM3076E/
ADM3077E/ADM3078E driver slew rates are not limited,
making possible transmit speeds of up to 16 Mbps. The
ADM3072E/ADM3075E/ADM3078E are half-duplex transceivers; the ADM3070E/ADM3071E/ADM3073E/ADM3074E/
ADM3076E/ADM3077E are each full-duplex transceivers. All
devices operate from a single 3.3 V supply. Drivers are output
short-circuit current limited, and thermal shutdown circuitry
protects drivers against excessive power dissipation. When
activated, the thermal shutdown circuitry places the driver
outputs into a high impedance state.

ADM3071E/ADM3074E/ADM3077E
The ADM307xE family guarantees a logic high receiver output
when the receiver inputs are shorted, open, or connected to a
terminated transmission line with all drivers disabled. This is
done by setting the receiver input threshold between −50 mV
and −200 mV. If the differential receiver input voltage (A − B) is
greater than or equal to −50 mV, RO is logic high. If A − B is
less than or equal to −200 mV, RO is logic low. In the case of a
terminated bus with all transmitters disabled, the receiver
differential input voltage is pulled to 0 V by the termination.
With the receiver thresholds of the ADM307xE family, this
results in a logic high with a 50 mV minimum noise margin.

HOT-SWAP CAPABILITY
(ALL EXCEPT ADM3071E/ADM3074E/ADM3077E)
Hot-Swap Inputs
When a circuit board is inserted into a hot, or powered,
backplane, differential disturbances to the data bus can lead to
data errors. During this period, processor logic output drivers
are high impedance and are unable to drive the DE and RE
inputs of the RS-485 transceivers to a defined logic level.
Leakage currents up to ±10 μA from the high impedance state
of the processor logic drivers can cause standard CMOS enable
inputs of a transceiver to drift to an incorrect logic level.
Additionally, parasitic circuit board capacitance can cause
coupling of VCC or GND to the enable inputs. Without the hotswap capability, these factors can improperly enable the driver
or receiver of the transceiver. When VCC rises, an internal pulldown circuit holds DE low and RE high. After the initial powerup sequence, the pull-down circuit becomes transparent,
resetting the hot-swap tolerable input.
carried out while device power is applied. This type of testing is
more representative of a real-world input/output discharge,
which occurs when equipment is operating normally.
The transmitter outputs and receiver inputs of the ADM307xE
family are characterized for protection to a ±15 kV limit using
the human body model.
HUMAN BODY MODEL
Figure 33 shows the human body model and the current
waveform it generates when discharged into a low impedance.
This model consists of a 100 pF capacitor charged to the ESD
voltage of interest, which is then discharged into the test device
through a 1.5 kΩ resistor.

Although very little energy is contained within an ESD pulse,
the extremely fast rise time, coupled with high voltages, can
cause failures in unprotected semiconductors. Catastrophic
destruction can occur immediately as a result of arcing or
heating. Even if catastrophic failure does not occur immediately,
the device can suffer from parametric degradation that can
result in degraded performance. The cumulative effects of
continuous exposure can eventually lead to complete failure.
Input/output lines are particularly vulnerable to ESD damage.
Simply touching or connecting an input/output cable can result
in a static discharge that damages or completely destroys the
interface product connected to the input/output port. It is
extremely important, therefore, to have high levels of ESD
protection on the input/output lines.
The ESD discharge can induce latch-up in the device under test,
so it is important that ESD testing on the input/output pins be

Two coupling methods are used for ESD testing: contact
discharge and air-gap discharge. Contact discharge calls for a
direct connection to the unit being tested. Air-gap discharge
uses a higher test voltage but does not make direct contact with
the test unit. With air-gap discharge, the discharge gun is
moved toward the unit under test, developing an arc across the
air gap, therefore the term air-gap discharge. This method is
influenced by humidity, temperature, barometric pressure,
distance, and rate of closure of the discharge gun. The contact
discharge method, while less realistic, is more repeatable and is
gaining acceptance and preference over the air-gap method.

256 TRANSCEIVERS ON THE BUS
The standard RS-485 receiver input impedance is 12 kΩ
(1 unit load), and the standard driver can drive up to 32 unit
loads. The ADM307xE family of transceivers has an ⅛ unit
load receiver input impedance (96 kΩ), allowing up to 256
transceivers to be connected in parallel on one communication line. Any combination of these devices and other RS-485
transceivers with a total of 32 unit loads or fewer can be
connected to the line.
REDUCED EMI AND REFLECTIONS
The ADM3070E/ADM3071E/ADM3072E feature reduced slew
rate drivers that minimize EMI and reduce reflections caused by
improperly terminated cables, allowing for error-free data
transmission at rates up to 250 kbps. The ADM3073E/
ADM3074E/ADM3075E offer higher driver output slew rate
limits, allowing for transmit speeds of up to 500 kbps.

LOW POWER SHUTDOWN MODE
(ALL EXCEPT ADM3071E/ADM3074E/ADM3077E)
Low power shutdown mode is initiated by bringing both RE
high and DE low. In shutdown mode, the device draws less than
1 μA of supply current. RE and DE can be driven simultaneously, but the parts are guaranteed not to enter shutdown if
RE is high and DE is low for fewer than 50 ns. If the inputs are
in this state for 600 ns or more, the parts are guaranteed to enter
shutdown. Enable times tZH and tZL assume the part was not
originally in a low power shutdown state (see the Test Circuits
and Switching Characteristics section). Enable times tZH(SHDN)
and tZL(SHDN) assume the part was originally shut down. It takes
drivers and receivers longer to become enabled from low power
shutdown mode (tZH(SHDN), tZL(SHDN)) than from driver/receiver
disable mode (tZH, tZL).
DRIVER OUTPUT PROTECTION
The ADM307xE family features two methods to prevent
excessive output current and power dissipation caused by faults
or by bus contention. Current limit protection on the output
stage provides immediate protection against short circuits over
the whole common-mode voltage range (see Figure 12 and
Figure 13). In addition, a thermal shutdown circuit forces the
driver outputs into a high impedance state if the die temperature rises excessively.
TYPICAL APPLICATIONS
The ADM3072E/ADM3075E/ADM3078E transceivers are
designed for bidirectional data communications on multipoint
bus transmission lines. Figure 34 shows a typical network
applications circuit. The ADM3071E/ADM3074E/ADM3077E
transceivers are designed for point-to-point transmission lines
(see Figure 35). The ADM3070E/ADM3073E/ADM3076E
transceivers are designed for full-duplex RS-485 networks (see
Figure 36).
To minimize reflections, terminate the line at both ends
with a termination resistor (the value of the termination
resistor should be equal to the characteristic impedance of
the cable used) and keep stub lengths off the main line as
short as possible.
