Driver/Receiver

EIA 232–E and CCITT V.28

(Formerly RS–232–D)

Legacy Device: Motorola MC145406

The ML145406 is a silicon–gate CMOS IC that combines three drivers and

three receivers to fulfill the electrical specifications of standards EIA 232–E

and CCITT V.28. The drivers feature true TTL input compatibility,

slew–rate–limited output, 300–Ω power–off source impedance, and output typ-

ically switching to within 25% of the supply rails. The receivers can handle up

to 25 V while presenting 3 to 7 kΩ impedance. Hysteresis in the receivers

aids reception of noisy signals. By combining both drivers and receivers in a

single CMOS chip, the ML145406 provides efficient, low–power solutions for

EIA 232–E and V.28 applications.
