Texas Instruments 74ALVCH32245ZKER
This 32-bit noninverting bus transceiver is designed for 1.65-V to 3.6-V VCC operation.
The SN74ALVCH32245 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.
To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors with the bus-hold circuitry is not recommended.
