MC14C88B
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 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.
