资 源 简 介

The 74HC/HCT240 are high-speed Si-gate CMOS devicesand are pin compaTIble with low power Schottky TTL(LSTTL). They are specified in compliance with JEDECstandard no. 7A.The 74HC/HCT240 are octal inverTIng buffer/line driverswith 3-state outputs. The 3-state outputs are controlled bythe output enable inputs 1OE and 2OE. A HIGH on nOEcauses the outputs to assume a high impedanceOFF-state. The “240” is idenTIcal to the “244” but hasinverTIng outputs.
