General Description
The UM202EExE 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. 


FEATUREs
● ESD Protection for RS-232 Bus Pins up to ±15kV Human Body Model
● Single +5V power supply
● Low power, ICC 15mA maximum
● Operates up to 250Kbps
● Receiver Noise Filter
● Latch-Up Performance Exceeds 200mA


APPLICATIONs
● Notebook and Palmtop Computers
● Battery-Powered Equipment
● Hand-Held Equipment
● POS terminal
