74ACQ374SJX

Overview

The MM74ACQ374SJX is an octal D-type flip-flop manufactured by onsemi, belonging to the 74ACQ logic series. It features a single-ended input and single-ended output configuration with non-inverting polarity. The device operates within a supply voltage range of 2V to 6V and supports surface-mount installation in a SOP-20 package. Key electrical characteristics include a maximum propagation delay of 8.5ns at 5V with 50pF load, a clock frequency of 90MHz, and output currents of 24mA for both high and low states. The static current (Iq) is specified at 40µA, and the input capacitance is 4.5pF.

Feature Summary

• Octal D-type flip-flop architecture providing eight independent data storage elements within a single integrated circuit.
• High-speed ACQ technology enabling operation up to 90MHz clock frequency with minimal propagation delay.
• Three-state output capability allowing direct bus interfacing and controlled signal driving without external components.

Applications

• Parallel-to-serial data conversion circuits
• Register banks in digital processing systems
• Buffering and latching applications in high-speed logic designs

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status and material composition details prior to integration. Ensure the specific suffix matches required packaging specifications. Check for obsolescence notices as availability may be limited. Validate pinout compatibility with existing PCB layouts during procurement planning.

Selection Notes

Select this component when high-speed performance and low power consumption are critical requirements. The 74ACQ series offers superior speed compared to standard HC or HCT families while maintaining CMOS input compatibility. Consider the SOP-20 package for surface-mount assembly needs. Evaluate the 2V to 6V operating range against system power constraints. Verify that the 24mA drive current meets load requirements for connected downstream logic gates.

Part Context

This part belongs to the 74ACQ family, which represents advanced CMOS technology optimized for high-speed applications. It serves as a successor to earlier 74AC series devices, offering improved switching speeds and lower power dissipation. The octal configuration allows efficient handling of wide data buses in compact form factors suitable for modern electronic equipment.

Replacement Considerations

Publicly confirmed substitute part numbers include CD74AC374E from Texas Instruments and SN74AC374N from Texas Instruments. These alternatives provide similar functional characteristics and pinouts for direct replacement in compatible designs.
