MOTOROLA ANALOG IC DEVICE DATA
The MC14C89B and MC14C89AB are low monolithic quad line receivers
using bipolar technology, which conform to the EIA–232–E, EIA–562 and
CCITT V.28 Recommendations. The outputs feature LSTTL and CMOS
compatibility for easy interface to +5.0 V digital systems. Internal
time–domain filtering eliminates the need for external filter capacitors in most
cases.
The MC14C89B has an input hysteresis of 0.35 V, while the MC14C89AB
hysteresis is 0.95 V. The response control pins allow adjustment of the
threshold level if desired. Additionally, an external capacitor may be added
for additional noise filtering.
The MC14C89B and MC14C89AB are available in both a 14 pin
dual–in–line plastic DIP and SOIC package.
