MC74LCX74MELG

Flip Flops Overview

The MC74LCX74MELG is a dual D-type flip-flop manufactured by onsemi, belonging to the 74LCX logic family. It operates within a supply voltage range of 2 V to 3.6 V and features single-ended inputs with differential outputs. The component is housed in a 14-pin SOEIAJ surface-mount package. Key electrical parameters include a propagation delay of 8 ns, high-level output current of -24 mA, and low-level output current of 24 mA. It supports an operating temperature range from -40°C to +85°C.

Flip Flops Feature Summary

• Dual D-type flip-flop configuration for sequential logic applications
• Differential output capability for signal integrity
• Compatible with 2V to 3.6V CMOS power supplies

Flip Flops Applications

• Data storage and register circuits
• Shift registers
• Timing control systems

Flip Flops Procurement Notes

Verify the specific suffix 'MELG' against official datasheets to confirm the SOEIAJ-14 package type and RoHS compliance status. Ensure that the ordering information matches the manufacturer's current production specifications, as suffixes can denote variations in packaging or material composition.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop is required for low-voltage (2V–3.6V) digital designs. The SOEIAJ-14 package is suitable for space-constrained surface-mount applications. Verify that the 8 ns propagation delay meets the system timing requirements and that the 24 mA drive current is sufficient for the load conditions.

Flip Flops Part Context

This part belongs to the MC74LCX74 series, which provides dual D-type flip-flops. It is distinct from other variants like the MC74LCX74DG, which utilizes a standard SOIC-14 package instead of the SOEIAJ-14 form factor found in the MELG variant. Both share similar electrical characteristics but differ in physical dimensions and mounting style.

Flip Flops Replacement Considerations

The MC74LCX74DG is a confirmed substitute part number offering identical logical functionality. However, it uses a SOIC-14 package rather than the SOEIAJ-14 package of the MC74LCX74MELG. Designers must verify footprint compatibility before substitution.
