VHiM3221EiP-1Y
RS232C-DRIVER
This is a single driver, single receiver RS-232 solution operating from a
single Vcc supply. The RS-232 pins provide IEC G1000-4-2 ESD Pro-
tection. The device meets the requirements of TIA/EIA-232-F and pro-
vides the electrical interface between an asynchronous communication
controller and the serial-port connector. The charge pump and four small
external capacitors allow operation from a single 3V to 5.5V supply.
