Product Details
| Description The ST485E is a 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 latch-up. These parts contain one driver and one receiver in half duplex configuration. This transceiver draws 300µA (typ.) of supply current when unloaded or fully loaded with disabled drivers. General features ■ Low quiescent current: 300µA ■ Designed for RS-485 interface application ■ -7V to 12V common mode input voltage range ■ Driver maintains high impedance in 3-state or with the power OFF ■ 70mV typical input hysteresis ■ 30ns propagation delay, 5ns skew ■ Operates from a single 5V supply ■ Current limiting and thermal shutdown for driver overload protection ■ ESD protection: – ±15KV (H.B.M.) – ±8KV (IEC-1000-4-2 contact discharge) ■ Allows up to 64 transceivers on the bus |
