description

This 32-bit noninverting bus transceiver is designed for 1.65-V to 3.6-V V

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 V through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

The SN74ALVCH32245 is characterized for operation from –40°C to 85°C.
