描述 Description

The UCD4093B device is designed for 3V to 15V VCCoperation, but is designed specifically for 0.5V to 20V VCCoperation.This device consists of four Schmitt trigger circuits. Eachcircuit functions as a two-input NAND gate with Schmitt triggeraction on both inputs. The gate switches at different points forpositive and negative going signals. The difference between thepositive voltage (VT+) and the negative voltage(VT-) is defined ashysteresis voltage(VH).This device is fully specified for partial-power-downapplications using IOFF. The IOFF circuitry disables the outputs,preventing damaging current backflow through the device when itis powered down.

特性 Features

Schmitt trigger action on each input with no external components Hysteresis voltage typically 0.9V at VDD=5V and 2.3V at VDD=10V Noise immunity greater than 50% No limit on input rise and fall times Standardized, symmetrical output characteristics 5V, 10V and 15V parametric ratings
