Quad Low Power Line Driver

The MC14C88B is a low power monolithic quad line driver, using BiMOS technology, which conforms to EIA–232–D, EIA–562, and CCITT V.28. The inputs feature TTL and CMOS compatibility with minimal loading. The outputs feature internally controlled slew rate limiting, eliminating the need for external capacitors. Power off output impedance exceeds 300 Ω, and current limiting protects the outputs in the event of short circuits.

Power supply current is less than 160 μA over the supply voltage range of ±4.5 to ±15 V. EIA–232–D performance is guaranteed with a minimum supply voltage of ±6.5 V.

The MC14C88B is pin compatible with the MC1488, SN75188, SN75C188, DS1488, and DS14C88. This device is available in 14 pin plastic DIP, and surface mount packaging.
