ST485E General 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 onedriver and one receiver in half duplex configuration.
This transceiver draw 300A (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).

ST485E Maximum Ratings

Symbol	Parameter	Value	Unit
V_CC	Supply Voltage	7	V
V_I	Control Input Voltage (RE, DE)	-0.5 to (V _CC+ 0.5)	V
V_DI	Driver Input Voltage (DI)	-0.5 to (V_CC + 0.5)	V
V_DO	Driver Output Voltage (A, B)	± 14	V
V_RI	Receiver Input Voltage (A, B)	± 14	V
V_RO	Receiver Output Voltage (RO)	0.5 to (V_CC + 0.5)	V

AbsoluteMaximum Ratings are those values beyond which damage to the device may occur. Functional operation under thesecondition is not implied.
