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.

Features

1. Schmitt trigger input discrimination

2. Standardized symmetrical output characteristics

3. Complies with JEDEC standard JESD 13-B

Applications

1. Wave and pulse shapers

2. Astable multivibrators

3. Monostable multivibrators
