SN74HC374N

Flip Flops Overview

The SN74HC374N is an octal D-type flip-flop with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features a PDIP-20 through-hole package. The device includes eight edge-triggered D-type flip-flops, providing non-inverting data transfer on the positive clock transition. Key electrical parameters include a maximum propagation delay of 230 ns at 2 V, high-level output current of -7.8 mA, and low-level output current of 7.8 mA. It supports a maximum operating temperature of +85 °C and minimum of -40 °C.

Flip Flops Feature Summary

• Octal configuration containing eight independent D-type flip-flops for parallel data storage
• Three-state outputs allow direct connection to bus systems without external pull-up components
• Positive-edge triggering ensures data capture occurs specifically on the rising clock signal
• Wide supply voltage compatibility ranging from 2 V to 6 V for diverse logic interface requirements

Flip Flops Applications

• Buffer registers for temporary data storage in digital circuits
• I/O port interfaces for connecting microcontrollers to peripheral devices
• Bidirectional bus drivers for managing data flow on shared communication lines
• Working registers within sequential logic systems

Flip Flops Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance standards required for your assembly process. Cross-reference the datasheet revision date to validate parameter accuracy. Confirm that the supplier provides traceable origin documents consistent with Texas Instruments manufacturing records. Check for any specific handling instructions related to static sensitivity during procurement and storage.

Flip Flops Selection Notes

Select this component when designing systems requiring wide voltage operation between 2 V and 6 V. Choose the SN74HC374N over other series if lower power consumption is critical compared to TTL-based alternatives. Consider the PDIP-20 package only if through-hole mounting is mandated by mechanical constraints. Evaluate the propagation delay characteristics against system timing requirements before finalizing the design choice.

Flip Flops Part Context

This part belongs to the SN74HC374 family of octal flip-flops. It shares functional similarities with the SN74HCT374N but differs in input threshold levels and supply voltage ranges. The HC series utilizes CMOS technology, offering higher noise immunity and lower power dissipation than standard TTL variants. It serves as a fundamental building block for complex digital memory structures and data path management in embedded applications.

Flip Flops Replacement Considerations

The SN74HCT374N offers similar functionality but requires a 4.5 V to 5.5 V supply and has TTL-compatible inputs. The SN74F374N provides faster switching speeds but operates strictly at 5 V. Verify pinout compatibility and electrical characteristics before substituting these alternatives.
