HEF4093B
Quad 2-input NAND Schmitt trigger
Rev. 8 — 21 November 2011
Product data sheet
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 (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.
2. Features and benefits
