74AC74SC

Overview

The onsemi 74AC74SC is a dual D-type edge-triggered flip-flop in the 74AC logic series. It features single-ended inputs and differential outputs with inverting and non-inverting polarities. The device operates within a supply voltage range of 2 V to 6 V, supporting a maximum clock frequency of 160 MHz. Propagation delay is specified at 6 ns. Output drive capability provides 24 mA for both high and low states. It is housed in a 14-SOIC surface-mount package and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual D-type edge-triggered flip-flops with set and reset functionality
• Differential output configuration providing complementary signals
• High-speed operation up to 160 MHz with 6 ns propagation delay
• Robust 24 mA output drive current capability

Applications

• Digital data storage and register circuits
• Sequential logic control systems
• High-speed signal processing interfaces

Procurement Notes

Verify the specific suffix 'SC' confirms the SOIC-14 surface-mount package variant. Confirm RoHS compliance status through official documentation as requirements vary by region. Check for obsolescence notices or lifecycle changes directly from onsemi before finalizing procurement plans.

Selection Notes

Select this component when dual independent D-type storage with differential outputs is required in a compact surface-mount form factor. Ensure the design supports the 2V to 6V operating range and utilizes the 14-SOIC footprint. Verify that the 160 MHz speed rating meets the system timing constraints.

Part Context

This part belongs to the 74AC family of advanced CMOS logic devices, offering higher speed than standard 74LS equivalents while maintaining compatibility. The 74AC74 specifically integrates two independent flip-flops, distinguishing it from single-element variants like the 74AC74A or different package options such as the PDIP version.

Replacement Considerations

Cross-reference with MC74AC74DTR2G for TSSOP-14 surface-mount alternatives. Consider 74AC74PC for through-hole DIP-14 requirements. Verify pinout and electrical specifications match exactly before substitution.
