SN74HC374NS

Flip Flops Overview

The SN74HC374NS is an octal edge-triggered 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 supports a maximum clock frequency of 70 MHz. The device utilizes a 20-pin SOIC package for surface-mount installation. Key electrical characteristics include a propagation delay of 230 ns at 2 V and output drive currents of ±7.8 mA. It functions with non-inverting polarity and CMOS input types, ensuring compatibility with standard logic interfaces.

Flip Flops Feature Summary

• Octal configuration providing eight independent edge-triggered D-type flip-flops in a single integrated circuit
• Three-state outputs enable direct connection to bus systems without additional interface components
• High current drive capability allows operation with high capacitive or low impedance loads

Flip Flops Applications

• Buffer registers for data storage and isolation
• I/O port expansion in embedded systems
• Bidirectional bus drivers for data transmission lines
• Working registers in digital processing circuits

Flip Flops Procurement Notes

Verify the specific suffix against official documentation to confirm package type and reel specifications. Ensure the ordering code matches the required tape-and-reel format for automated assembly. Cross-reference the manufacturer part number with the latest datasheet revision to confirm pinout and electrical parameters remain unchanged before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems requiring parallel data latching with bus-compatible outputs. The HC series offers low power consumption suitable for battery-operated devices. Verify that the operating voltage range aligns with the system's power supply rails. Consider the SOIC package dimensions for PCB layout constraints and thermal management requirements during the design phase.

Flip Flops Part Context

This device belongs to the SN74HC374 family of octal D-type flip-flops. It shares functional similarities with other members like the SN74HC374N but differs in packaging technology. The NS suffix specifically denotes the surface-mount SOIC variant, distinguishing it from through-hole DIP options within the same logical family.

Flip Flops Replacement Considerations

Direct substitutes include the SN74HC374DWR and SN74HC374DR, which offer identical functionality in compatible SOIC packages. Verify pin-to-pin compatibility and electrical specifications before swapping components in existing designs.
