IDT74FCT244TPY

Overview

The IDT74FCT244TPY is an octal buffer and line driver manufactured by Integrated Device Technology. It operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range of -40°C to 85°C. The device features TTL-compatible CMOS inputs with 3-state outputs, providing high drive capability with output currents of 15mA (high) and 64mA (low). It utilizes a 20-pin SSOP surface-mount package.

Feature Summary

• Provides true TTL input and output compatibility for seamless integration with legacy logic families.
• Features low input and output leakage current, typically less than 1mA maximum.
• Operates at standard CMOS power levels while delivering robust signal buffering capabilities.

Applications

• High-speed data bus driving applications requiring 3-state control.
• Clock distribution networks in digital systems.
• Memory interface buffering between microprocessors and storage devices.

Procurement Notes

Verify the specific suffix 'TPY' corresponds to the 20-lead SSOP package variant when sourcing. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards, as older IDT batches may vary. Ensure the supplier provides traceability documentation for integrated circuit authenticity.

Selection Notes

Select this component when an octal buffer with 3-state outputs is required for TTL-to-CMOS interfacing. It is suitable for designs needing moderate drive strength with low power consumption. Consider thermal management for the SSOP package if operating near the upper temperature limit.

Part Context

This part belongs to the FCT (Fast CMOS Technology) family from IDT, designed for high-speed digital applications. It serves as a direct replacement for similar octal buffers in systems requiring reliable signal integrity and compatibility with both TTL and CMOS logic levels.

Replacement Considerations

The TI CY74F244T is a functional equivalent offering similar electrical characteristics and pinout compatibility. Verify package dimensions and electrical tolerances before substitution to ensure system performance remains within specifications.
