SN74HC374DW

Flip Flops Overview

The SN74HC374DW is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It features eight non-inverting D-type flip-flops with three-state outputs, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 2 V to 6 V and supports a maximum clock frequency of 70 MHz. Typical propagation delay is 15 ns at 6 V with 50 pF load, while maximum delay reaches 230 ns at 2 V. Output drive capability includes ±7.8 mA for both high and low states. Static current consumption is typically 8 µA. Operating temperature range spans from -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent edge-triggered D-type flip-flops on a single chip
• Three-state outputs enable direct bus driving without additional interface components
• CMOS input structure ensures low static power consumption and high noise immunity

Flip Flops Applications

• Buffer registers for data storage and isolation
• I/O port implementations in embedded systems
• Bidirectional bus drivers for system interconnects
• Working registers in digital logic circuits

Flip Flops Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-20 surface mount package variant. Confirm RoHS compliance status as indicated in official documentation. Check lead time availability through authorized distributors. Ensure ordering quantities match tube packaging specifications provided by Texas Instruments. Validate component authenticity via manufacturer traceability records.

Flip Flops Selection Notes

Select this component when an octal register with tri-state output capability is required. Consider the HC series speed and voltage compatibility with existing system logic levels. Evaluate thermal performance within the specified operating temperature range. Compare pinout compatibility with alternative packages if board space constraints exist. Verify input capacitance requirements against source driver capabilities.

Flip Flops Part Context

This part belongs to the SN74HC374 family of octal D-type flip-flops. It is part of Texas Instruments' broader 74HC logic product line designed for CMOS applications. The device complements other members like SN74HC374N (PDIP) and SN74HC374DWR (tape/reel). It serves as a standard solution for parallel data storage in general-purpose digital designs.

Flip Flops Replacement Considerations

SN74HC374DWR offers identical electrical characteristics in tape-and-reel packaging. SN74HC374N provides the same functionality in through-hole PDIP-20 package. SN74HCS374DW is available for applications requiring Schmitt-trigger inputs instead of standard CMOS inputs.
