74HCT374N,652

Overview

The NXP USA Inc. 74HCT374N,652 is an octal D-type flip-flop featuring positive-edge triggering and single-ended inputs with tri-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V. The device exhibits a maximum propagation delay of 32 ns at 4.5 V under a 50 pF load capacitance. Designed for through-hole mounting, it utilizes a 20-pin PDIP package measuring 26.92 mm in length, 6.4 mm in width, and 3.2 mm in height. The component supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Octal D-type flip-flop architecture with eight independent storage elements per chip
• Positive-edge triggering mechanism for data capture on clock transitions
• Tri-state output configuration enabling bus-oriented system designs
• CMOS HCT logic family compatibility ensuring TTL-level input interfacing

Applications

• Parallel-to-serial data conversion circuits
• Bus latch applications for temporary data storage
• Register stages in digital signal processing systems

Selection Notes

Select this component when designing systems requiring high-density octal storage with tri-state capabilities. Ensure the design accommodates the 4.5 V minimum supply voltage for proper HCT operation. Consider the 32 ns propagation delay for timing closure in synchronous circuits. The wide operating temperature range supports industrial environments, while the PDIP package facilitates prototyping and through-hole assembly processes.

Part Context

This part belongs to the Nexperia (formerly NXP Standard Product) 74HCT series of logic devices. The company transitioned its standard product business to Nexperia in February 2017, though legacy NXP branding may persist in documentation. The 74HCT374N,652 represents a specific variant within the broader octal flip-flop family, distinguished by its through-hole packaging and specific electrical characteristics defined by the HCT logic standard.
