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.","metaTitle":"SN75C189ADR RS232 Receiver – TI Active 14-SOIC","metaDescription":"Texas Instruments SN75C189ADR RS232 receiver, 0/4 drivers/receivers, 970 mV hysteresis, 4.5V–6V supply, 14-SOIC.
