DUAL 2-INPUT POSITIVE-OR
GATE
DESCRIPTION
The U74LVC2G32 is a dual 2-input OR gate which performs the
function Y=A+B or Y=A *B . It is designed for 1.65V to 5.5V
operation.
FEATURES
* Wide Supply Voltage Range from 1.65V to 5.5V
* Max tPD of 3.8 ns at 3.3V
* Up to 5.5V Inputs Accept Voltages
* Low Power Consumption, ICC = 10 μA (Max.)
* ±24 mA Output Driver at 3.3V
* Typical VOLP (Output Ground Bounce) < 0.8V,
VCC = 3.3 V, TA = 25 °C
* Typical VOHV (Output VOH Undershoot) > 2V,
VCC = 3.3 V, TA = 25 °C

Note: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
