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 (V_P) and the negative voltage (V_N) is defined as hysteresis voltage (V_H) (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).

cd4093b由四个施密特触发器电路。每个电路起两个输入与非门的作用，在两个输入端都有Schmitt触发器动作。门开关在不同的点，正负信号。正向电压之间的差值（VP）和负电压（越南）被定义为滞后电压（VH）（见图2）。
的cd4093b类型14引线密封双列直插陶瓷封装提供（F3A后缀），14导联线塑料封装（后缀的双E），14引脚小外形封装（M，MT，M96星系，和NSR的后缀），和14引脚超薄紧缩小外形封装（PW和压水堆后缀）。
