DESCRIPTION

The UTC UT213 consists of 4 drivers and 5 receivers. It meets

ElA/TIA-232 and V.28/V.24 specifications, it intended for notebook

computer applications. A high-efficiency, dual charge-pumps power supply

and a low-dropout transmitter combine to deliver true RS-232 performance

from a single +3.0V~+5.5V power supply. A guaranteed data rate of

250kbps provides compatibility with popular software for communicating

with PCs.

The UTC UT213 has an active-low shutdown and an active-high

receiver enable control. Two receivers of the UTC 213 are active, allowing

the ring indicator(RI)to be monitored easily using only 75uW power.

The UTC UT213 requires only 0.1µF capacitors in 3.3V operation, and

can operate from input voltages ranging from +3.0V ~+5.5V. It is ideal for

3.3V-only systems, 5.0V-only systems, or mixed 3.3V and 5.0V systems

that require true RS-232 performance.
