CD74ACT273MPWREP

Overview

The CD74ACT273MPWREP is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the ACT logic series. It features eight independent D-type flip-flops with a master reset function and non-inverting outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a 20-pin TSSOP package for surface-mount installation. Designed for high-speed applications, it supports propagation delays typical of the ACT family under standard loading conditions.

Feature Summary

• Contains eight independent D-type flip-flops with master reset functionality
• Features non-inverting outputs compatible with TTL input levels
• Operates within a wide voltage range suitable for 5V systems
• Utilizes advanced CMOS technology for high-speed performance

Applications

• Parallel-to-serial data conversion circuits
• Shift register configurations in digital systems
• Memory address latching applications
• General-purpose storage elements in microprocessor interfaces

Procurement Notes

Verify the specific suffix 'REP' against the manufacturer's official documentation to confirm it denotes a recognized engineering sample or restricted production variant rather than a standard commercial grade part. Ensure that the TSSOP-20 package dimensions match your PCB footprint requirements precisely. Confirm availability status directly with authorized distributors as this specific suffix may indicate limited stock or special handling procedures distinct from standard inventory items.

Selection Notes

Select this component when designing systems requiring octal storage with fast switching speeds and robust noise immunity. The ACT series offers superior performance compared to older HCT or LVC families while maintaining compatibility with standard 5V logic levels. Consider the TSSOP package for space-constrained designs where surface-mount technology is preferred over through-hole alternatives like the PDIP variant.

Part Context

This part belongs to the Texas Instruments CD74ACT273 family of octal D-type flip-flops. It shares functional similarities with other members like the CD74ACT273M96 but differs in packaging and potentially in manufacturing lot specifications due to the REP suffix. It serves as a core building block for sequential logic circuits requiring parallel data capture and synchronous output control in industrial and consumer electronics.
