Product details

RS232 line receiver – what the 970 mV hysteresis buys you

The SN75C189ADR is a quad RS232 receiver in a 14-SOIC package. Its 970 mV of hysteresis filters noise on long cable runs — a common source of false bit edges in serial links. With 0 drivers and 4 receivers, it is a pure receive-side device, not a transceiver.

Supply range and temperature grade – BOM-fit check

Operates from a single 4.5V to 6V rail, which maps directly to a 5V ±10% supply — no extra regulator needed.
