HEF4093B Datasheet – Quad 2-Input NAND Schmitt Trigger

Part Number: HEF4093B

Function: Quadruple 2-input NAND Schmitt trigger

Package: SOIC 14 Pin

Manufacturer: NXP Semiconductors.


HEF4093B datasheet



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 (Vt+) and the negative voltage (Vt-) is defined as hysteresis voltage (Vh).

It operates over a recommended Vdd power supply range of 3 V to 15 V referenced to Vss (usually ground). Unused inputs must be connected to Vdd, Vss, or another input.



1. Schmitt trigger input discrimination
