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 differ-
ence between the positive (V
T
+
) and the negative voltage
(V
T
-
) 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).

Note 1: "Absolute Maximum Ratings" are those values beyond which the
safety of the device cannot be guaranteed; they are not meant to imply that
the devices should be operated at these limits. The table of "Recom-
mended Operating Conditions" and "Electrical Characteristics" provides
conditions for actual device operation.
