Product details

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.
Even in the standby mode, 2 receiver circuits can operate as inverters without hysteresis width. The other 2 circuits are fixed at a high level.
