CY74FCT240ATSOCT

Overview

The CY74FCT240ATSOCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight inverting inputs driving three-state outputs within a 20-pin SOIC package. The device operates on a supply voltage ranging from 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 4.8 ns at 5 V, high-level output current of -32 mA, and low-level output current of 64 mA. It supports surface mount installation with an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides buffering and line driving capabilities for digital signals
• Features inverting logic polarity for signal inversion applications
• Supports three-state output control for bus system isolation

Applications

• Bus-oriented systems requiring signal buffering
• Memory address drivers for data buses
