Description
General part information
ST485 Series
The ST485ERB is a low-power transceiver for RS-485 and RS-422 communication. Each driver output and receiver input is protected against ±15 kV electrostatic discharge (HBM) ± 8 kV (IEC-1000-4-2 contact discharge) shocks, without latch-up. These parts contain one driver and one receiver.
This transceiver draws 300 µA (typ.) of supply current when unloaded or fully loaded with disabled drivers.
It operates from a single 5 V supply.
