description/ordering information
The CD4093B 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) (see Figure 2).
The CD4093B is available in 14-lead small-outline plastic package (M96) and 14-lead thin shrink small-outline
packages (PWR suffixes).
