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 difference between

the positive (VTa) and the negative voltage (VTb) 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
