74VCX132 Low Voltage Quad 2-Input NAND Gate with Schmitt Trigger Inputs and 3.6V Tolerant Inputs and Out-
General Description
The VCX132 contains four 2-input NAND gates with
Schmitt Trigger Inputs. The pin confi guration and function
are the same as the VCX00 except the inputs have hysteresis between the positive-go ing and negative-going input
thresholds. This hysteresis is useful for transforming slowly
switching input signals into sha rply defined, jitter-free output signals. This prod uct sho uld b e u sed w her e n oise ma rgin greater than that of conventional gates is required.
The VCX132 is de signed for low voltage (1.6 5V to 3.6V)
applications with I/O compatibility up to 3.6V.
