DESCRIPTION

The UTC UT3223 consists of 2 drivers and 2 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 UT3223 achieves 1µA supply current in shutdown

condition. When the UT3223 doesn’t detect a valid signal level on its

receiver inputs, the on-board power supply and drivers will shutdown,

and when a valid level is applied to any 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 UT3223 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.


