SN74HC374NG4

Flip Flops Overview

The SN74HC374NG4 is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It features eight independent D-type flip-flops with three-state outputs, designed for high-capacitance or low-impedance loads. The device operates within a supply voltage range of 2 V to 6 V and supports through-hole mounting in a 20-PDIP package. Key electrical parameters include a maximum propagation delay of 230 ns at 2 V and 39 ns at 6 V (with 150 pF load). Output drive capabilities are specified as ±7.8 mA at 5 V, with a maximum static current of 8 µA. The component functions over an extended temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent edge-triggered D-type flip-flops for parallel data storage
• Three-state outputs enable direct bus driving without additional interface components
• High-current outputs designed to drive high capacitance or low impedance loads
• Low power consumption with minimal static current draw during operation

Flip Flops Applications

• Buffer registers for temporary data storage in digital systems
• I/O port expansion for microcontroller interfaces
• Bidirectional bus drivers for shared data lines

Flip Flops Procurement Notes

Verify the G4 suffix indicates RoHS compliance and lead-free construction per Texas Instruments standards. Confirm the PDIP-20 package matches your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power supply specifications. Check that the propagation delay meets your timing constraints for the intended clock frequency.

Flip Flops Selection Notes

Select this component when an octal register with tri-state capability is required. The HC series offers CMOS compatibility with standard TTL input levels. Consider the 20-PDIP package for prototyping or through-hole assembly needs. Verify that the 2V to 6V supply range suits your application's power budget and noise immunity requirements.

Flip Flops Part Context
