UM232EExE High ESD-Protected, Fail-Safe, Single Supply RS-232 Transceivers UM232EESE SOP16 UM232EEPE DIP16 UM232EEUE TSSOP16 General Description The UM232EExE series are low power single supply RS232 interface. The device consists of two line drivers, two line receivers, and 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. The device operates at data signaling rates over 250kbps.
