SN74AHC374NSR

Flip Flops Overview

The SN74AHC374NSR is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the AHC logic series. It features eight edge-triggered D-type flip-flops with three-state outputs in a 20-SOIC package. The device operates within a supply voltage range of 2V to 5.5V. Key electrical parameters include a propagation delay of 10.1ns at 5V with 50pF load, a maximum clock frequency of 120MHz, and output drive currents of 8mA for both high and low states. Static current consumption is 4µA. It supports surface-mount installation and functions across a temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Contains eight positive-edge-triggered D-type flip-flops with non-inverting three-state outputs
• Utilizes advanced AHC technology for high-speed operation and low power consumption
• Provides symmetrical output drive capabilities with 8mA source and sink currents
• Compatible with standard CMOS input levels and offers noise immunity

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file storage elements in digital systems
• Buffering and latching applications for data buses
• Timing synchronization and signal sampling stages

Flip Flops Procurement Notes

Verify the specific ordering suffix 'SR' confirms the reel packaging format and SOIC-20 physical dimensions. Ensure the component matches the SN74AHC374 family specifications rather than similar variants like AC or HC. Confirm RoHS compliance status and check for any recent product change notifications affecting manufacturing sites or materials before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems requiring moderate speed performance with low power dissipation. The 2V to 5.5V operating range allows flexibility in mixed-voltage environments. Consider the 10.1ns propagation delay and 120MHz clock limit against system timing requirements. The 8mA output drive is suitable for direct interfacing with standard loads without additional buffering.

Flip Flops Part Context

This part belongs to the Texas Instruments SN74AHC374 family of octal flip-flops. It shares functional similarities with the SN74AC374 but offers improved switching characteristics and lower power consumption typical of the AHC series. The NSR suffix indicates a surface-mount SOIC-20 package supplied in tape and reel format for automated assembly processes.

Flip Flops Replacement Considerations

• SN74AHC374DWR (Same family, different SOIC width)
• SN74AHC374PW (TSSOP-20 package variant)
