NOTES:

2. All Vcc pins must be connected to power supply.

3. All GND pins must be connected to ground.

4. Package body is approximately 14mm x 14mm x 1.4mm.

5. This package code is used to reference the package diagram.

6. This text does not indicate orientation of the actual part-marking.

Withaninputdataregister,theIDT70V9189/79hasbeenoptimizedfor

applicationshavingunidirectionalorbidirectionaldataflowinbursts.An

on-chip circuitry of each port to enter a very low standby power mode.

Fabricated using IDT’s CMOS high-performance technology, these

devices typically operate on only 500mW of power.
