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. The slew rate of driver is set internally less than

30V/μs and the receivers feature internal noise filtering, eliminating the need for external slew

rate and filter capacitors for reliable operation. The driver inputs and receiver outputs are TTL and

CMOS compatible. UM232EExE comes in 16 pin DIP, SOP and TSSOP packages, operating over

the commercial and industrial temperature ranges.

The ESD tolerance has been upgraded on these devices to over ±15KV for both Human Body

Model and IEC61000-4-2 Air Discharge Method, without latch-up. The device operates with four

0.1μF capacitors, reduce system cost and board space.
