UTRS3227数据手册UTC中文资料规格书

描述 Description

The UTC UTRS3227  consists of 1 driver and 1 receiver. It meetsElA/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 shutdowncondition. The UTC  UTRS3227 automatically enter a low-power shutdown mode when the RS-232 cable is disconnected or thetransmitters 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.
