HEF4093BP

The HEF4093BP is designed as quadruple 2-input NAND schmitt trigger which consists of four schmitt-trigger circuits. Each circuit functions as a two-input NAND gate with schmitt-trigger action on both inputs. The HEF4093BP gate switches at different points for positive and negative-going signals. The difference between the positive voltage and the negative voltage is defined as hysteresis voltage. It is 14-lead DIL and plastic (SOT27-1).

HEF4093BP has many applications and some examples are listed here. (1) Wave and pulse shapers. (2) Astable multivibrators. (3) Monostable multivibrators. And so on.
