MOS INTEGRATED CIRCUIT

FEATURES • Conforms to EIA/TIA-232-E (former name, RS-232C) standards • Selectable +3.3 V/+5 V single power supply (selected by VCHA pin) • By setting the standby pin to a low level (standby mode), circuit current can be reduced. At such times, the driver output is in a high-impedance state.
