SEMICONDUCTOR TECHNICAL DATA
Drivers/Receivers
EIA–232–E and CCITT V.28
and receiver to fulfill the electrical specifications of EIA Standard 232–E and
CCITT V.28. The drivers feature true TTL input compatibility, slew rate limiting
outputs, 300
within 25% of the supply rails. The receivers can handle up to
presenting 3 to 7 k impedance. Hysteresis in the receivers aid in the reception
of noisy signals. By combining both drivers and receivers in a single CMOS
chip, these devices provide efficient, low–power solutions for both EIA–232–E
and V.28 applications.
