SN74LVCZ32244A - 32-Bit Buffer/Driver with 3-State Outputs

This 32-bit buffer/driver is designed for 2.7-V to 3.6-V V_CC operation.

The SN74LVCZ32244A 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.

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.

During power up or power down, when V_CC is between 0 and 1.5 V, the device is in the high-impedance state. However, to ensure the high-impedance state above 1.5 V, OE\ should be tied to V_CC 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 I_CC and power-up 3-state. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down (V_CC = 0 V). The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict.
