The ST75185C is a single-chip solution with multiple RS-232 drivers and receivers. It meets and exceeds the requirements of EIA/TIA-232-E and ITU V.28 standards, and is designed to support data rates up to 120 kbps.
The ST75185C is an integrated circuit containing three drivers and five receivers designed to meet EIA/TIA-232-E and ITU V.28 standards. It features a DB9S-compatible pinout to reduce part count and board space when interfacing UARTs with serial port connectors on IBM PC/AT compatible systems.
The device operates over a temperature range of 0°C to 70°C and supports data rates up to 120 kbps, particularly with lower capacitive loads. It is available in SO-20 and TSSOP20 packages and includes bipolar circuits for ruggedness at the expense of higher quiescent power compared to CMOS alternatives.
