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).

Features:

• Qualified for Automotive Applications
