DESCRIPTION

The UTC UTRS3227 consists of 1 driver and 1 receiver. It meets

SSOP-16(150mil)

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 1Mbps for high speed applications such as

communicating with ISDN modems.

The UTC UTRS3227 achieves 1µA supply current in shutdown

condition. The UTC UTRS3227 automatically enter a low-power

shutdown mode when the RS-232 cable is disconnected or the

transmitters of the connected peripherals are inactive, and the UART

driving the transmitter inputs is inactive for more than 30 seconds.

The UTC UTRS3227 turn on again when they sense a valid

transition at any transmitter or receiver input.

The UTC UTRS3227 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.


