Part Number : HEF4093B
Function : Quadruple 2-input NAND Schmitt trigger
Manufacturers : NXP Semiconductors.
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.
