SN74HC374NE4

Flip Flops Overview

The SN74HC374NE4 is an octal D-type flip-flop featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and utilizes a 20-pin PDIP package for through-hole mounting. The device supports a wide operating temperature range from -40°C to +85°C. Key electrical parameters include a maximum propagation delay of 230 ns at 2 V and 39 ns at 6 V under specified load conditions. Output drive capabilities provide high-level and low-level currents of 7.8 mA each at 5 V. Static current consumption is typically 8 µA.

Flip Flops Feature Summary

• Octal configuration with eight edge-triggered D-type flip-flops for parallel data storage

Flip Flops Procurement Notes

Verify the ordering suffix NE4 indicates lead-free construction compliant with RoHS standards. Confirm the package type matches the required 20-pin DIP footprint for PCB layout. Ensure the voltage supply aligns with the 2 V to 6 V operational range. Check that the temperature rating meets environmental requirements. Validate the manufacturer source to guarantee component authenticity.

Flip Flops Selection Notes

Select this component when an octal latch with tri-state capability is required for bus interfacing. The HC series offers CMOS input compatibility suitable for various logic families. Consider the propagation delay specifications relative to system clock speeds. Evaluate the through-hole packaging requirement against available board space. Compare static power consumption benefits against alternative logic families for efficiency.

Flip Flops Part Context

This part belongs to the SN74HC374 family of octal D-type flip-flops. It shares functional similarities with other variants like SN74HC374N but includes specific manufacturing attributes indicated by the suffix.
