Description
The ST3485EB/EC/EI/EIY device is ±15 kV ESD
protected, 3.3 V low power transceiver for RS-
485 and RS-422 communications. The device
contains one driver and one receiver in half
duplex configuration.
The ST3485E device transmits and receives at a
guaranteed data rate of at least 12 Mbps.
All transmitter outputs and receiver inputs are
protected to ±15 kV IEC 61000-4-2 air discharge.
The driver is short-circuit current limited and is
protected against excessive power dissipation by
thermal shutdown circuitry that places the driver
outputs into a high impedance state.

Symbol
Name and function
1
RO
Receiver output. If A > B by 200 mV, RO will be high; if A < B by 200
mV, RO will be low.
2
RE
Receiver output enable. RO is enabled when RE is low; RO is high
impedance when RE is high. If RE is high and DE is low, the
device will enter a low power shutdown mode.
3
DE
Driver output enable. The driver outputs are enabled by bringing DE
high. They are high impedance when DE is low. If RE is high DE is
low, the device will enter a low-power shutdown mode. If the driver
outputs are enabled, the part functions as line driver, while they are
high impedance, it functions as line receivers if RE is low.
4
DI
Driver input. A low on DI forces output A low and output B high.
Similarly, a high on DI forces output A high and output B low.
5
GND
Ground.
6
A
Non-inverting receiver input and non-inverting driver output.
