The SN65C23243 and SN75C23243 consist of
RIN4B 23 26 ROUT4B two ports, each containing three line drivers and
RIN5B 24 25 ROUT5B five line receivers, and a dual charge-pump circuit with ±15-k V ESD protection pin to pin (serial-port connection pins, including GND). These devices meet the requirements of TIA/EIA-232-F and provide the electrical interface between an asynchronous munication controller and the serial-port connector. This bination of drivers and receivers matches that needed for two typical serial ports used in an IBM PC/AT, or patible. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V supply. In addition, these devices include an always-active noninverting output (ROUT2) per port, which allows applications using the ring indicator to transmit data while the devices are powered down. The devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/µs driver output slew-rate.
