SN74LVCH32245A 具有三态输出的 32 位总线收发器

This 32-bit (quad-octal) noninverting bus transceiver is designed for 1.65-V to 3.6-V VCC operation.

The SN74LVCH32245A is designed for asynchronous communication between data buses. The control-function implementation minimizes external timing requirements.

This device can be used as four 8-bit transceivers, two 16-bit transceivers, or one 32-bit transceiver. It allows data transmission 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 that the buses are effectively isolated.

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3
