SN74AVCAH164245 具有可配置电压转换的 16 位双电源总线收发器
This 16-bit (dual-octal) noninverting bus transceiver uses two separate configurable power-supply rails. The A-port is designed to track VCCA. VCCA accepts any supply voltage from 1.4 V to 3.6 V. The B-port is designed to track VCCB. VCCB accepts any supply voltage from 1.4 V to 3.6 V. This allows for universal low-voltage bidirectional translation between any of the 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.
The SN74AVCAH164245 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 outputs so the buses are effectively isolated
