Datasheet

1. General description
The HEF4093B is a quad two-input NAND gate. Each input has a Schmitt trigger circuit.
The gate switches at different points for positive-going and negative-going signals. The
difference between the positive voltage (V
T+
) and the negative voltage (V
T
) is defined as
hysteresis voltage (V
H
).
It operates over a recommended V
DD
power supply range of 3 V to 15 V referenced to V
SS
(usually ground). Unused inputs must be connected to V
DD
, V
SS
, or another input.
2. Features and benefits
 Schmitt trigger input discrimination
 Fully static operation
 5 V, 10 V, and 15 V parametric ratings
 Standardized symmetrical output characteristics
 Specified from40 C to +85 C and 40 C to +125 C
 Complies with JEDEC standard JESD 13-B
3. Applications
 Wave and pulse shapers
 Astable multivibrators
 Monostable multivibrators
