CD4093BC集成电路（IC）的门反相器规格书PDF中文资料

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 (VT+) and the negative voltage (VT−) 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

■ Wide supply voltage range: 3.0V to 15V

■ Schmitt-trigger on each input with no external components

■ Noise immunity greater than 50

■ Equal source and sink currents

■ No limit on input rise and fall time

■ Standard B-series output drive

■ Hysteresis voltage (any input) TA = 25°C

Typical

VDD = 5.0V VH = 1.5V

VDD = 10V VH = 2.2V

VDD = 15V VH = 2.7V

Guaranteed

VH = 0.1 VDD

Applications

• Wave and pulse shapers

• High-noise-environment systems
