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 W, and
current limiting protects the outputs in the event of short circuits.

Power supply current is less than 160 mA 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.

Features:

• BiMOS Technology for Low Power Operation (

t

5.0 mW)

• Meets Requirements of EIA–232–D, EIA–562, and CCITT V.28

• Quiescent Current Less Than 160
