## Description

The SN75C188 is a monolithic, low-power, quadruple line driver manufactured by Texas Instruments. It is designed to conform to ANSI Standard EIA/TIA-232-E and ITU Recommendation V.28, making it suitable for interfacing data terminal equipment (DTE) with data communications equipment (DCE).

Key electrical characteristics include a very low quiescent current of 95 µA typical and current-limited outputs of 10 mA typical. The device features CMOS- and TTL-compatible inputs and on-chip slew rate limiting to 30 V/µs maximum. It supports a flexible supply voltage range, characterized at ±4.5 V and ±15 V, with a typical operating supply voltage of ±12 V.

The SN75C188 is characterized for operation over a temperature range of 0°C to 70°C. It is functionally interchangeable with older parts like the SN75188, MC1488, and DS14C88. An external diode in series with each supply-voltage terminal is recommended for protection under certain fault conditions to comply with EIA/TIA-232-E.

Available in PDIP, SOIC, SOP, and SSOP packages, the SN75C188 is suitable for various board-level integration needs.
