SN74LVCC4245A中文资料具有可调节输出电压和三态输出的八路总线收发器数据手册TI规格书

描述 Description

This 8-bit (octal) noninverting bus transceiver uses two separate power-supply rails. The A port, VCCA, is dedicated to accept a 5-V supply level, and the configurable B port, which is designed to track VCCB, accepts voltages from 3 V to 5 V. This allows for translation from a 3.3-V to a 5-V environment and vice versa.

The SN74LVCC4245A is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE)\\ input can be used to disable the device so the buses are effectively isolated. The control circuitry (DIR,OE\\) is powered by VCCA.
