IDT74FCT2541TQ

Overview

The IDT74FCT2541TQ is an octal buffer/line driver belonging to the FCT series, manufactured using advanced dual metal CMOS technology. It features two functional blocks of four bits each, providing true output polarity within a single package. The device operates with a standard supply voltage and supports industrial temperature ranges. It is housed in a compact surface-mount TSSOP-20 package, designed for high-speed data transmission applications requiring low power consumption and robust signal integrity.

Feature Summary

• Octal configuration providing eight buffered outputs for efficient bus driving
• True TTL input and output compatibility ensuring seamless integration
• Low input and output leakage characteristics for reduced standby power
• High drive capability suitable for memory and I/O port interfacing

Applications

• Memory address buffering in computer systems
• I/O port expansion circuits
• Bus driver implementations for data lines
• Clock distribution networks

Procurement Notes

Verify the specific suffix 'TQ' against the manufacturer's official datasheet to confirm the exact package type and temperature grade. Ensure the component matches the required speed grade and electrical specifications for your design. Cross-reference the ordering part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when an octal buffer with high drive strength and low power consumption is required. It serves as a replacement for older ABT functions while offering improved performance metrics. Consider the TSSOP-20 package constraints and ensure the board layout supports the pinout configuration for optimal signal routing and thermal management.

Part Context

This device is part of the broader FCT logic family, which bridges the performance gap between standard CMOS and bipolar technologies. It is designed to replace legacy ABT series components, offering faster switching speeds and lower power dissipation. The FCT series is widely used in digital systems requiring reliable data storage and transfer capabilities.

Replacement Considerations

Compatible substitutes include IDT74FCT244TQ and IDT74FCT240TQ for similar buffering functions. Other manufacturers may offer equivalent parts under different naming conventions, but verification of pin compatibility and electrical parameters is essential.
