SN74HC374DBR

Flip Flops Overview

The SN74HC374DBR is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It features eight positive-edge triggered D-type flip-flops with tri-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 40 MHz. Key electrical parameters include a propagation delay of 230 ns at 2 V and 150 pF load, with output drive capabilities of ±7.8 mA. It functions within a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration containing eight independent positive-edge triggered D-type flip-flops for parallel data storage.
• Tri-state outputs allow direct connection to bus-oriented systems without additional interface logic.
• CMOS input structure ensures high noise immunity and low static power consumption across the operating voltage range.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffer register implementations
• I/O port interfacing
• Bidirectional bus drivers

Flip Flops Procurement Notes

Verify the suffix 'DWR' against datasheet specifications to confirm tape-and-reel packaging and pin compatibility. Ensure the order quantity aligns with standard reel sizes to avoid cut-tape premiums. Confirm RoHS compliance status matches current manufacturing standards before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems requiring eight-bit latching with bus-compatible tri-state outputs. The HC series offers broader voltage flexibility compared to HCT variants. Verify that the 20-pin SOIC footprint fits the PCB layout constraints and that the 40 MHz speed meets the system timing requirements.

Flip Flops Part Context

This part belongs to the SN74HC374 family of octal D-type flip-flops. It is functionally compatible with other industry-standard octal flip-flops but differs in specific electrical characteristics such as drive strength and switching speeds. The DBR suffix indicates a specific tape-and-reel packaging variant optimized for automated surface-mount assembly processes.

Flip Flops Replacement Considerations
