74HC374DB,112

Overview

The 74HC374DB,112 is an octal D-type flip-flop manufactured by Nexperia USA Inc., belonging to the HC logic family. It features eight positive-edge-triggered D-type flip-flops with three-state outputs in a 20-pin SSOP package. The device operates within a supply voltage range of 2.0 V to 6.0 V and supports propagation delays typical for high-speed CMOS applications. It includes output enable functionality for bus-oriented designs and complies with JEDEC standards for noise immunity and latch-up performance.

Feature Summary

• Octal configuration with eight independent D-type flip-flops
• Three-state outputs controlled by a common output enable input
• Positive-edge triggering for data capture on clock transitions
• High noise immunity and robust latch-up performance

Applications

• Bus-oriented memory mapping systems
• Parallel-to-serial data conversion circuits
• General-purpose register storage applications
• Interface buffering between microprocessors and peripherals

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications prior to procurement. Ensure packaging specifications match design requirements for surface-mount assembly processes.

Selection Notes

Select this component when requiring an octal flip-flop with three-state outputs in a compact SSOP package. Consider the HC series compatibility with standard CMOS logic levels and wide supply voltage ranges. Evaluate thermal performance and operating temperature limits against system environmental constraints.

Part Context

This part belongs to the 74HC374 family of octal D-type flip-flops. It shares functional characteristics with other variants like 74HCT374D but differs in input threshold levels and power consumption profiles. The DB suffix indicates the specific SSOP-20 package type used for surface-mount technology integration.

Replacement Considerations

Public confirmed substitute part numbers include 74HC374PW,118 and 74HCT374D. Verify pinout compatibility and electrical parameter alignment before substitution.
