DESCRIPTION
The ST485E is al low power transceiver for
RS-485 and RS-422 communication. Each driver
output and receiver input is protected against
±
15KV electrostatic discharge (H.B.M.) (ESD)
shocks, without latcup. These parts contain one
driver
configuration.
This transceiver draw 300
μ
A (typ.) of supply
current when unloaded or fully loaded with
disabled drivers.
It operates from a single 5V supply.
Driver is short-circuit current limited and is
protected against excessive power dissipation by
thermal shutdown circuitry that place the driver
outputs into a high-impedance state.
The ST485E is designed for bi-directional data
communications on multipoint bus transmission
line (half-duplex applications).
