RS-232-E
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
a
power-off source impedance, and output typically
switching to within 25% of the supply rails. The receivers can handle up to ± 25V while presenting 3 to
7 kn 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:
