DS14C89AMX Quad RS-232 Receiver For UART And Control Signals

DS14C89AMX is used to bring RS-232 level signals into a digital system cleanly, especially in legacy ports and industrial controllers that still depend on serial links. It implements four receiver channels, converting EIA/TIA-232-E compatible inputs into logic-level outputs for UARTs and control lines. DS14C89AMX includes failsafe behavior so open inputs bias to a known output state, which can reduce false toggling on disconnected cables. It supports a data rate of 20 kb/s, making it suitable for typical console, configuration, and service ports. Keep the input routing away from fast switching nodes and add proper protection if the cable can see ESD or miswiring. Place the device close to the connector to reduce noise pickup and clamp stress.
