Octal Buffer/Line Driver with 3-STATE Outputs

General Description

Features

The AC/ACT240 is an 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.

■ I_CCand I_OZreduced by 50%

■ Inverting 3-STATE outputs drive bus lines or buffer

memory address registers

■ Outputs source/sink 24 mA

■ ACT240 has TTL-compatible inputs
