UM202E/232E High ESD-Protected,Fail-Safe, Single Supply RS232 Transceivers General Description The UM202E/232E series are low power single supply RS232 interface. The device consists of two line drivers, two line receivers, and a dual charge pump circuit. The device meets the requirements of TIA/ EIA-232 standard and provides the electrical interface between an asynchronous communication controller and the serial-port connector. The on chip charge pump and four small external capacitors act as onboard DC to DC converter, allow chip operated from single 5V supply, eliminating the need for +/- 10V power supplies, reduce cost and board space. Chip power supply current is specified at 6.
