翻两番正与非门施密特触发器输入 QUADRUPLE POSITIVE-NAND GATES WITH SCHMITT-TRIGGER INPUTS
description/ordering information
Each circuit functions as a NAND gate, but because of the Schmitt action, it has different input
threshold levels for positive- and negative-going signals. The ’HC132 devices perform the Boolean
function Y = A •Bor Y = A+ Bin positive logic.
These circuits are temperature compensated and can be triggered from the slowest of input ramps and still give clean jitter-free output signals.
Wide Operating Voltage Range of 2 V to 6 V
Outputs Can Drive Up To 10 LSTTL Loads
Low Power Consumption, 20-µA Max ICC
Typical tpd = 14 ns
±4-mA Output Drive at 5 V
Low Input Current of 1 µA Max
Operation From Very Slow Input Transitions
Temperature-Compensated Threshold Levels
High Noise Immunity
Same Pinouts as ’HC00
