  • Product 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. 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. UM202EExE 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 ±8kV for Human Body Model and ±15kV IEC61000-4-2 Air Discharge Method, without latch-up. The device operates with four 0.1μF capacitors, reduce system cost and board space.
