CD4093BM CD4093BC Quad 2-Input NAND Schmitt Trigger
February 1993
CD4093BM CD4093BC Quad
2-Input NAND Schmitt Trigger
General Description
The CD4093B consists of four Schmitt-trigger circuits Each
circuit functions as a 2-input NAND gate with Schmitt-trigger
action on both inputs The gate switches at different points
for positive and negative-going signals The difference be-
tween the positive (V
T
a
) and the negative voltage (V
T
b
) is
defined as hysteresis voltage (V
H
)
All outputs have equal source and sink currents and con-
form to standard B-series output drive (see Static Electrical
Characteristics)
