Philips HEF4093B
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.DESCRIPTION
The difference between the positive voltage (VP) and the negative voltage (VN) is defined as hysteresis voltage (VH). Product specification HEF4093B gates Fig.2 Pinning diagram.
