Storage Considerations
These are stress ratings only and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications is
not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.
Storage in a low humidity environment is preferred. Large
high density plastic packages are moisture sensitive and
should be stored in Dry Vapor Barrier Bags. Prior to usage,
the parts should remain bagged and stored below 40°C
and 60%RH. If the parts are removed from the bag, they
should be used within 48 hours or stored in an environment at or below 20%RH. If the above conditions cannot
be followed, the parts should be baked for four hours at
125°C in order remove moisture prior to soldering. Zywyn
ships product in Dry Vapor Barrier Bags with a humidity
indicator card and desiccant pack. The humidity indicator
should be below 30%RH.

ZT4xxE
Circuit Description
Bus Configuration
The ZT483E, ZT485E, ZT489E, ZT490E, and ZT491E are
low-power transceivers for RS-485 and RS-422 communications. The RS-485 standard is ideal for multi-drop applications and for long-distance interfaces. The TIA/EIA-485
specification allows up to 32 drivers and 32 receivers to be
connected to a data bus, making it an ideal choice for multidrop applications. RS-485 transceivers are equipped with a
wide (-7V to +12V) common mode range to accommodate
ground potential differences since the cabling can be as
long as 4,000 feet. As RS-485 is a differential interface, data
is virtually immune to noise in the transmission line.
The ZT483E, ZT488E, and ZT489E are slew-rate limited,
minimizing EMI and reducing reflections caused by improperly terminated cables.
The ZT489E, ZT490E, and ZT491E are full-duplex transceivers, while the ZT483E and ZT485E are half-duplex.
For full duplex, the devices are used as a four-wire bus
transceiver with a configuration that the transmitters and
receivers are moving data independent of each other. Transmit can occur on a dedicated two-wire pair and receive can
occur on an adjacent two-wire pair, with each pair transferring data at up to 10Mbps (up to 250kbps for the ZT489E).
Half duplex is a configuration where the transmitter outputs
are connected to its receiver inputs. This application is
common for two-wire interfaces where either the transmitter
is active or the receiver is active. It is common to connect
the enable inputs for the transmitter and receiver together so
that a logic HIGH will enable the transmitter and disable the
receiver. Conversely, a logic LOW will disable the transmitter and enable the transmitter. Half-duplex configuraitons
and these devices are designed for bidirectional data transmission on multipoint twisted-pair cables for applications,
such as digital motor controllers, remote sensors and
terminals, industrial process control, security stations and
environmental control systems.
RS-485 Transmitters
Each device in the ZT4xxE family contains a differential
output line transmitter that can drive voltage into multiple
loads on a terminated two-wire pair, and a receiver that
accepts a differential voltage down to 200mV. The
transmitter's differential output can comply with RS-485 and
also RS-422 standards. The typical voltage output swing
with no load is 0V to VCC. With worst case loading of 54
ohms across the differential outputs, the drivers can maintain greater than 1.5V voltage levels, which is more than
adequate for a differential receiver to acknowledge a logic
state. The 54 ohms is the equivalent of two 120 ohm
termination resistors placed on each side of the transmission line and the input impedance of 32 receivers on the line.
The ZT485E transmitter has an enable control line which is
active HIGH. A logic HIGH on DE (pin 3) will enable the
differential outputs. A logic LOW on DE (pin 3) will disable
the transmitter outputs. While disabled, the transmitter
outputs are in high impedance.
ESD Immunity
Electro-Static Discharge (ESD) is an important factor when
implementing a serial port into a system, especially in harsh
environmental conditions. These industrial strength devices provide extra protection against ESD and are intended
for harsh environments where high-speed data communication is important.
All of the ZT485E family of transceivers incorporate internal
protection structures on all pins to protect against ESD
charges encountered during handling and assembly. The
driver outputs and receiver inputs have extra protection
against static electricity as they are directly interfacing to
the outside environment. As such, these pins against ESD
of ±15kV without damage in all states of the transceiver's
operation in the static state. After multiple ESD events,
Zywyn’s ZT485E family of transceivers keep working without
latchup. These devices eliminate the need for external
transient suppressor diodes and the associated high capacitance loading, allowing reliable high-speed data communications.
The Human Body Model has been the generally accepted
ESD testing method for semiconductors. This test is intended to simulate the human body’s potential to store
electrostatic energy and discharge it to an integrated circuit
upon close proximity or contact. This method will test the
IC’s capability to withstand an ESD transient during normal
handling such as in manufacturing areas where the ICs tend
to be handled frequently.
RS-485 Receivers
Each transceiver contains one differential receiver that has
an input sensitivity of 200mV. The input impedance of the
receivers is typically 15 kohms. A wide common mode
range of -7V to +12V allows for large ground potential
differences between systems.
The ZT485E, ZT489E, and ZT491E receivers have an enable
control input. A logic LOW on RE will enable the receiver,
a logic HIGH on RE will disable the receiver. The receivers
are equipped with the fail-safe feature, which guarantees
that the receiver output will be in a HIGH-IMPEDANCE state
when the input is left unconnected.
The ZT485E, ZT490E, and ZT491E can transmit and receive
at data rates up to 10Mbps. The ZT483E, ZT488E, and
ZT489E are specified for data rates up to 250kbps.
