74ACQ240PC集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

General Description

The ACQ/ACTQ240 is an inverting octal buffer and line driver designed to be employed as a memory address driver, clock driver and bus oriented transmitter or receiver which provides improved PC board density. The ACQ/ACTQ utilizes Fairchild’s Quiet Series technology to guarantee quiet output switching and improve dynamic threshold performance. FACT Quiet Series™ features GTO output control and undershoot corrector in addition to a split ground bus for superior performance.

特性 Features

■ ICC and IOZ reduced by 50

■ Guaranteed simultaneous switching noise level and

dynamic threshold performance

■ Guaranteed pin-to-pin skew AC performance

■ Improved latch-up immunity

■ Inverting 3-STATE outputs drive bus lines or buffer

memory address registers

■ Outputs source/sink 24 mA

■ Faster prop delays than the standard ACT240
