Pin Configuration(1,2,3)

NOTES:

1. A15X is a NC for IDT709079.

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

3. All GND pins must be connected to ground supply.

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

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

Withaninputdataregister,theIDT709089/79hasbeenoptimizedfor

applications having unidirectional or bidirectional data flow in bursts.

An automatic power down feature, controlled by CE0and CE1, permits

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

mode. Fabricated using CMOS high-performance technology, these

devices typically operate on only 950mW of power.
