32-Bit Buffer/Driver With 3-State Outputs

This 32-bit Buffer driver is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVCH322244A is designed specifically to improve the performance and density of 3-state memory address drivers, Clock Drivers and bus-oriented receivers and transmitters.
The device CAN be used as eight 4-bit Buffers four 8-bit Buffers two 16-bit Buffers or one 32-bit Buffer It provides true outputs and symmetrical active-low output-enable (OE) inputs.
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.
The outputs, which are designed to sink up to 12 mA, include equivalent 26- resistors to reduce overshoot and undershoot.
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.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
