UT3221/E

CMOS IC

+3.0V TO +5.5V POWER

SUPPLY, 250KBPS,

MULTICHANNAEL RS-232

LINE DRIVER/RECEIVER



DESCRIPTION

The UTC UT3221/E consists of 1 driver and 1 receiver. 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 UT3221/E achieves 1µA supply current in shutdown

condition. When the UT3221/E doesn’t detect a valid signal level

on its receiver input, the on-board power supply and driver will

shutdown, and when a valid level is applied to RS-232 receiver

input, then the system turns on again. Therefore, the system saves

power without changes to the existing BIOS or operating system.

The UTC UT3221/E 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.


