IDT74FCT273TQ

Overview

The IDT74FCT273TQ is an octal D-type flip-flop register built using advanced dual-metal CMOS technology. It features eight edge-triggered storage elements with individual data inputs and outputs, sharing a common buffered clock and master reset input. The device provides true TTL input and output compatibility, ensuring reliable interfacing with standard logic families. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 20-pin SSOP package.

Feature Summary

• Octal D-type flip-flop configuration with independent data inputs and outputs
• Common buffered clock and master reset inputs for simultaneous control
• True TTL input and output compatibility with low leakage currents
• High drive output capability supporting standard load conditions

Applications

• Parallel-to-serial data conversion circuits
• General-purpose 8-bit register storage applications
• I/O buffering and interface isolation between logic levels
• Timing synchronization and data latching in digital systems

Procurement Notes

Verify the specific suffix 'TQ' against manufacturer documentation to confirm the SSOP package type and speed grade. Ensure the component matches the required operating temperature range and voltage specifications for your design. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and current production status before procurement.

Selection Notes

Select this component when an octal register with common control signals is required. It is suitable for designs needing high-speed data latching with TTL-compatible interfaces. Consider the SSOP package constraints for PCB layout. Verify that the propagation delay and drive current meet the system timing and load requirements compared to alternative FCT series devices.

Part Context

This component belongs to the 74FCT logic family, which combines the speed of bipolar logic with the low power consumption of CMOS technology. The 74FCT273 variant specifically provides octal D-type flip-flops. Integrated Device Technology (IDT) manufactures this series, now part of Renesas Electronics, focusing on high-performance logic solutions for embedded applications.

Replacement Considerations

Compatible substitutes include CY74FCT273TQ from Texas Instruments and PI74FCT273TQ from Pericom/Diodes Incorporated. These parts share identical logical functionality and pinouts. Verify package dimensions and electrical characteristics match the original design requirements before substitution.
