CD4093BC
Quad 2-Input NAND Schmitt Trigger
■ Equal source and sink currents
■ No limit on input rise and fall time
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 (VT+) and the negative voltage
(VT−) is defined as hysteresis voltage (VH).
■ Standard B-series output drive
■ Hysteresis voltage (any input) TA = 25°C

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
