CD74FCT240ATM

Overview

The CD74FCT240ATM is a bus driver from the FCT series, manufactured by Harris Corporation. It features two independent functions, each handling four bits of data with inverted output polarity. The device utilizes CMOS technology and is housed in a PDSO20 package. It operates within a temperature range of -40 °C to 85 °C. Key electrical characteristics include a maximum low-level output current of 0.064 A and a load capacitance of 50 pF. The control type is enabled low, and the outputs are three-state.

Feature Summary

• Provides dual 4-bit bus driving capability with inverted logic outputs
• Features three-state outputs controlled by a low-active enable signal
• Incorporates bus hold inputs to eliminate the need for external pull-up resistors

Applications

• High-speed data bus buffering applications
• Clock distribution networks requiring inverted signals
• Memory interface circuits utilizing FCT logic families

Procurement Notes
