CD4093B

CMOS 四路 2 输入与非施密特触发器

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 Fig. 2.

The CD4093B types are supplied in 14-lead hermetic dual-in-line ceramic packages F3A suffix, 14-lead dual-in-line plastic packages E suffix, 14-lead small-outline packages M, MT, M96, and NSR suffixes, and 14-lead thin shrink small-outline packages PW and PWR suffixes.
