SN74LVC4245A-EP 具有三态输出的增强型产品八路总线收发器和 3.3V 至 5V 转换器

This 8-bit (octal) noninverting bus transceiver contains two separate supply rails; B port has VCCB, which is set at 3.3 V, and A port has VCCA, which is set at 5 V. This allows for translation from a 3.3-V to a 5-V environment, and vice versa.

The SN74LVC4245A 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 SN74LVC4245A pinout allows the designer to switch to a normal all-3.3-V or all-5-V 20-pin ’245 device without board re-layout. The designer uses the data paths for pins 2-11 and 14-23 of the SN74LVC4245A to align with the conventional ’245 pinout
