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).

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

APPLICATIONs
■ Wave and pulse shapers
■ Astable multivibrators
■ Monostable multivibrators
