Quadruple 2-input NAND Schmitt trigger

DESCRIPTION

The HEF4093B consists of four Schmitt-trigger circuits.

Each circuit functions as a two-input NAND gate with

Schmitt-trigger action on both inputs. The gate switches at

different points for positive and negative-going signals.

The difference between the positive voltage (VP) and the

negative voltage (VN) is defined as hysteresis voltage

(VH).
