SN74AHCT374NSRG4

Flip Flops Overview

The SN74AHCT374NSRG4 is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It belongs to the 74AHCT logic family, designed for high-speed CMOS operation with standard TTL-compatible inputs. The device features eight independent D-type flip-flops with a common clock and output enable control. It operates within a supply voltage range of 4.5 V to 5.5 V. The component is housed in a 20-pin Small Outline Package (SOIC) with a width of 7.5 mm. It supports surface-mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single package
• TTL-compatible input thresholds enabling direct interfacing with standard logic families
• Edge-triggered data storage synchronized by a positive-going clock pulse
• Output enable functionality allowing tri-state control for bus-oriented applications

Flip Flops Applications

• Parallel-to-serial or serial-to-parallel data conversion circuits
• Register arrays for temporary data storage in digital systems
• Shift register configurations for sequential logic operations
• Bus interface drivers requiring controlled output states

Flip Flops Procurement Notes

Verify the specific ordering suffix 'G4' to confirm RoHS compliance status as defined by the manufacturer. Ensure the SOIC-20 package dimensions match the target PCB footprint requirements. Confirm that the 4.5 V to 5.5 V supply voltage range aligns with the system power design. Check current availability status as production lifecycle stages may affect long-term sourcing options.

Flip Flops Selection Notes

Select this component when TTL-compatible inputs are required alongside high-speed CMOS performance. The AHCT series bridges the gap between older TTL standards and modern low-power CMOS technologies. Consider the 20-pin SOIC package for prototyping or manufacturing where surface-mount technology is preferred over through-hole alternatives.

Flip Flops Part Context

This part is a member of the Texas Instruments 74AHCT family, which combines the speed of AC logic with the compatibility of HCT inputs. It serves as a successor to legacy 74HCT devices while offering improved switching characteristics. The octal flip-flop architecture is standard for managing multiple data lines simultaneously in complex digital designs.

Flip Flops Replacement Considerations

SN74AHCT374NSR is the non-RoHS compliant equivalent without the G4 suffix. SN74AHCT374DR is the tape-and-reel variant in the same package. SN74AHCT374N is the through-hole DIP alternative. Verify pinout compatibility before substituting.
