U74LVC1G99

DESCRIPTION 

The U74LVC1G99 is a configurable multiple functions with 

3-state output device, and when output-enable (OE) input is 

high ,the output is disabled, when OE is low, the output state is

determined by 16 patterns of 4-bit input. The user can choose 

different logic functions 

Such as AND, OR, NAND, NOR, XOR, XNOR, MUX, inverter, 

and buffer, by changing the inputs’ logic state. All inputs can be 

connected to VCC or GND. 

The device have different input threshold levels for positivegoing (VT+) and negative-going(VT-) signals because of the 

Schmitt-trigger action in the input.

This device has power-down protective circuit, preventing device 

destruction when it is powered down. 

FEATURES 

* Operate from 1.65V to 5.5V 

* Inputs accept voltages to 5.5V 

* All inputs have Schmitt-trigger action

* Low power dissipation: ICC=10μA(Max.) 

* Max tPD of 6.7 ns at 3.3V 

* ±24mA output drive(VCC=3.3V) 

* Offers nine different logic functions in a single package
