U74AVC1T45数据手册UTC中文资料规格书

描述 Description

This single-bit noninverting bus transceiver uses two separate configurable power-supply rails. The UTC U74AVC1T45 is optimized to operate with VCCA/VCCB set at 1.4V to 3.6V. It is operational with VCCA/VCCB as low as 1.2 V. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2V to 3.6V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.2V to 3.6V. This allows for universal low-Voltage, bidirectional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V voltage nodes.
