EIA–232–E and CCITT V.28
These devices are silicon gate CMOS ICs that combine both the transmitter
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
power–off source impedance, and output typically switching to
within 25% of the supply rails. The receivers can handle up to
±
25 V while
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.
These devices offer the following performance features:
