The SN75C188DR from Texas Instruments is a monolithic, low-power, quadruple line driver conforming to ANSI Standard EIA/TIA-232-E and ITU Recommendation V.28. This device is built with Bi-MOS technology, offering compatibility with both TTL and CMOS logic levels.
Key electrical characteristics include a flexible supply voltage range of ±4.5V to ±15V, a typical quiescent current of 95 μA, and current-limited outputs of 10 mA. The on-chip slew rate is limited to a maximum of 30 V/μs. It features CMOS- and TTL-compatible inputs and is designed to interface data terminal equipment (DTE) with data communications equipment (DCE).
This line driver is characterized for operation within an ambient temperature range of 0°C to 70°C. It is supplied in a 14-SOIC package suitable for surface mounting. An external diode is recommended in series with each supply-voltage terminal for protection under certain fault conditions, as per EIA/TIA-232-E compliance.
The SN75C188DR is functionally interchangeable with parts like the Texas Instruments SN75188, Motorola MC1488, and National Semiconductor DS14C88, making it a versatile choice for various communication interface applications.
