abbreviatedto GR.
This 16-bitis designed for 1.65-Vto
3.6-V VCC operation.
The SN74ALVCH162244is designed specificallyto
improve the and density of 3-state
memory address drivers, clock drivers, and
bus-oriented and transmitters.
symmetrical output-enable (OE) inputs.
The outputs, are designedto sinkupto12 mA, include equivalent 26-Ω resistorsto reduce overshoot and
undershoot. ensure the state during power upor down, OE should be tiedto VCC througha pullup
resistor; the valueof the resistoris determined the current-sinking capabilityof the driver.
Active bus-hold circuitryis providedto hold unusedor floating data inputsata valid logic level.
The SN74ALVCH162244is characterizedfor operation -40°Cto 85°C.
