74LVQ74SJX

Overview

The onsemi 74LVQ74SJX is a dual D-type flip-flop integrated circuit belonging to the LVQ logic series. It features two independent positive-edge-triggered elements, each with one bit of data storage. The device operates within a supply voltage range of 2V to 3.6V and supports surface-mount installation in a 14-SOP package. Key electrical specifications include a maximum propagation delay of 14ns at 3.3V with 50pF load, output currents of 12mA for both high and low states, and a static current of 20µA. It functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual D-type flip-flop architecture with positive-edge triggering
• Integrated set (preset) and reset functionality
• Complementary output types for versatile signal interfacing

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose digital storage applications

Procurement Notes

This component is officially designated as obsolete and no longer manufactured by onsemi. Procurement must focus on verifying the authenticity of remaining stock from authorized distributors or secondary market sources. Buyers should confirm the specific manufacturing date code and ensure compliance with RoHS requirements before acquisition, as availability is limited and subject to existing inventory constraints.

Selection Notes

Engineers requiring this specific part number must evaluate end-of-life status implications for long-term production stability. Selection should prioritize finding verified surplus stock or identifying direct pin-compatible replacements from other manufacturers that maintain equivalent LVQ series performance characteristics. Verify that substitute components match the 14-SOP footprint and 2V-3.6V operational voltage range to ensure seamless integration into existing designs.

Part Context

The 74LVQ74SJX belongs to onsemi's LVQ logic family, designed for low-voltage CMOS applications. As a dual D-type flip-flop, it provides essential sequential logic capabilities in compact surface-mount packaging. This specific variant represents a legacy product within the broader 74LVQ series portfolio, which has been succeeded by newer generations offering enhanced performance metrics.

Replacement Considerations

Public confirmed substitute part numbers include Texas Instruments SN74LVC74ANSR.
