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 (VT
+) and the negative voltage
(VT
−) is defined as hysteresis voltage (VH).
All outputs have equal source and sink currents and con-
form to standard B-series output drive (see Static Electrical
Characteristics).
Features
- Wide supply voltage range: 3.0V to 15V
- Schmitt-trigger on each input
with no external components
- Noise immunity greater than 50%
- Equal source and sink currents
- No limit on input rise and fall time
- Standard B-series output drive
- Hysteresis voltage (any input) TA = 25°C
Applications
•Wave and pulse shapers
•High-noise-environment systems
