Description

This 32-bit buffer/driver SN74LVC32244 is designed for 1.65-V to 3.6-V VCC operation.

The SN74LVC32244 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 SN74LVC32244 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.

SN74LVC32244 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.

This device SN74LVC32244 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.

To ensure the high-impedance state during power up or power down, SN74LVC32244 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.
