16-BIT BUFFER/DRIVER WITH

3-STATE OUTPUTS



DESCRIPTION

This 16-bit buffer/driver is designed for 1.65V to 3.6V VCC

operation.

The U74LVC16244A 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 four 4-bit buffers, two 8-bit buffers,

or one 16-bit buffer. It provides true outputs and symmetrical

active-low output-enable ( OE ) inputs.

Inputs can be driven from either 3.3V or 5V devices. This

feature allows the use of this device as a translator in a mixed

3.3V/5V system environment.

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.

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.



FEATURES

* Wide supply voltage range from 1.65V to 3.6V

* Inputs accept voltages up to 5.5V

* IOFF supports partial-power-down mode

* Low static power consumption; ICC=10μA (Max.)
