32-Bit Bus Transceiver With 3-State Outputs

This 32-bit (quad-octal) noninverting Bus Transceiver is designed for 2.7-V to 3.6-V VCC operation.
The SN74LVCZ32245A 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 3.3-V/5-V system environment.
When VCC is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 1.5 V, 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.
This device is fully specified for hot-insertion applications using Ioff and power-up 3-state. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict.
