CD4093BCMX

四2输入与非门 Quad 2-input NAND Gate

General Description

The CD4093B consists of four Schmitt-trigger circuits. Each circuit functions as a 2-input NAND gate with Schmitt trigger action on both inputs. The gate switches at different

points for positive and negative-going signals. The differ ence between the positive

VT+ and the negative voltageVT− is defined as hysteresis voltage VH.All outputs have equal source and sink currents and conform to standard B-series output drive see Static Electrical Characteristics.

Features
