GENERAL DESCRIPTION
The AD7306 line driver/receiver is a 5 V monolithic product
which provides an interface between TTL signal levels and dual
standard EIA RS-232/RS-422 signal levels. The part contains
two RS-232 drivers, one RS-422 driver, one RS-232 receiver,
and one receiver path which can be configured either as RS-232
or as RS-422.
An internal charge pump voltage converter facilitates operation
from a single +5 V power supply. The internal charge pump
generates ± 10 V levels allowing RS-232 output levels to be developed without the need for external bipolar power supplies.
A highly efficient charge pump design allows operation using
non polarized, miniature 0.1 µF capacitors. This gives a considerable saving in printed circuit board space over conventional
products which can use up to 10 µF capacitors. The charge
pump output voltages may also be used to power external circuitry which requires dual supplies.

The RS-232 channels are suitable for communications rates up
to 100 kHz and the RS-422 channels are suitable for high speed
communications up to 5 MHz. The RS-422 transmitter complementary outputs are closely matched and feature low timing
skew between the complementary outputs. This is often an essential requirement to meet tight system timing specifications.
All inputs feature ESD protection, all driver outputs feature
high source and sink current capability and are internally protected against short circuits on the outputs. An epitaxial layer is
used to guard against latch-up.
The part is available in a 24-lead SOIC and 24-pin plastic DIP
package.

*Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those listed in the
operational sections of this specification is not implied. Exposure to absolute
maximum ratings for extended periods of time may affect device reliability.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD7306 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

AD7306
GENERAL DESCRIPTION
RS-232 Drivers
The AD7306 drivers/receivers provide an interface which is
compatible with RS-232/RS-422 standard interfaces. As both
standards are widely accepted it is often necessary to provide an
interface which is compatible with both. The AD7306 is ideally
suited to this type of application as both standards may be met
using a single package. This part contains two RS-232 drivers,
one RS-422 driver, one RS-232 receiver, and one receiver path
which can be configured as either RS-232 or RS-422. This receiver is configured using the 232/422 SEL pin.
The RS-232 drivers in the AD7306 meet the EIA RS-232
specifications. The drivers are inverting level shifters which
convert TTL/CMOS levels into RS-232 output levels. The input switching threshold is typically 1.3 V. With a typical
RS-232 load, the output levels are ± 7.5 V. Under worst case
load conditions, the drivers are guaranteed to provide ± 5 V
which meets the minimum RS-232 requirement. The output
slew rate is internally limited to <30 V/µs without the need for
an external slew limiting capacitor. Short circuit protection is
also provided which prevents damage in the event of output
fault conditions. Active current limiting is used which limits the
output short circuit current to less than 12 mA in the event of
an output fault. This type of current limiting does not degrade
the output voltage swing under normal loading conditions as
would be the case with conventional passive limiting.
This part also contains an internal charge pump voltage converter which facilitates operation using a single +5 V power
supply.
Charge Pump DC-DC Voltage Generator
The charge pump voltage generator uses a switched capacitor
technique to develop ± 10 V levels from an input +5 V supply. A
highly efficient charge pump design coupled with a high frequency internal oscillator permit operation using four 0.1 µF
capacitors.

The powered-down output impedance is typically 10 MΩ. This
is considerably larger than the 300 Ω minimum value required
by the RS-232 specification. It provides additional protection
under fault conditions where another powered-up transmitter
output is inadvertently shorted to the powered-down device.

OUTPUT
RS-232 Receivers
The receivers are inverting level shifters which accept RS-232
input levels (± 3 V to ± 15 V) and translates them into 5 V
TTL/CMOS levels. The input switching thresholds are 0.8 V
minimum and 2.4 V maximum which are well within the
RS-232 requirement of ± 3 V. Internal 5 kΩ pull-down resistors
to GND are provided on the receiver inputs. This ensures that
an unconnected input will be interpreted as a low level giving a
Logic “1” on the TTL/CMOS output. Excellent noise immunity is achieved by the use of hysteresis and internal filtering
circuitry. The filter rejects noise glitches of up to 0.5 µs in
duration.

Figure 7. Charge Pump Voltage Generator
Capacitors C1 and C2 act as charge storage capacitors while C3
and C4 provide output smoothing. For correct operation all four
capacitors must be included. Either polarized or nonpolarized
capacitors may be used for C1–C4. If a polarized type is used,
then the correct polarity should be observed. This may be ignored with nonpolarized type capacitors.
RS-422 Driver
The RS-422 driver on the AD7306 accepts a TTL/CMOS input and translates it into a differential RS-422 level signal. The
input switching threshold is typically 1.3 V. The unloaded output differential voltage is typically ± 5 V (see Typical Performance Characteristics). Short circuit protection is provided on
the output which limits the current to less than 150 mA.
The charge pump output voltages, V+ and V–, are used internally to power the RS-232 transmitters. This permits RS-232
output levels to be developed on the RS-232 transmitter outputs. The charge pump output voltages may also be used to
power external circuitry if the current requirements are small.
Please refer to the Typical Performance Characteristics.
RS-422 Receiver
The RS-422 receiver on the AD7306 accepts a differential input signal and translates it into a TTL/CMOS output level.
The input resistance on both differential inputs is 5 kΩ typical.
With the receiver inputs unconnected (floating), internal biasing ensures that the receiver output is a Logic “1.”
The generator rise time after power up is 200 µs typical. This
time is necessary to completely charge the storage capacitors in
the charge pump. Therefore, RS-232 data transmission should
not be initiated until this time has elapsed after switch on. This
will ensure that valid data is always transmitted.
Excellent noise immunity and high transmission speed is
achieved using the differential configuration.

Single-Ended Data Transmission
Differential Data Transmission
Single-ended interfaces are used for low speed, short distance
communications such as from a computer terminal to a printer.
A single line is used to carry the signal. Various standards have
been developed to standardize the communication link, the most
popular of these being the RS-232. The RS-232 standard was
introduced in 1962 by the EIA and has been widely used
throughout the industry. The standard has been revised several
times, and the current revision is known as EIA-232E. The
RS-232 standard is suitable for single-ended data transmission
at relatively slow data rates over short distances. A typical
RS-232 interface is shown in Figure 14.
When transmitting at high data rates, over long distances and
through noisy environments, single-ended data transmission is
often inadequate. In this type of application, differential data
transmission offers superior performance. Differential transmission uses two signal lines to transmit data. It rejects ground
shifts and is insensitive to noise signals which appear as common mode voltages on the transmission lines. To accommodate
faster data communication, the differential RS-422 standard was
developed. Therefore, it can be used to reliably transmit data at
higher speeds and over longer distances than single-ended transmission. A typical RS-422 interface is shown in Figure 15.
