MC74LCX74DR2G

Flip Flops Overview

The MC74LCX74DR2G is a dual D-type flip-flop from onsemi's 74LCX logic family, designed for low-voltage CMOS applications. It operates within a supply voltage range of 2 V to 3.6 V and features differential outputs with inverting and non-inverting polarities. The device is housed in a 14-SOIC package and supports surface-mount installation. Key electrical parameters include a maximum propagation delay of 8 ns at 50 pF load, high-level output current of -24 mA, and low-level output current of 24 mA. It functions reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Dual D-type flip-flop architecture with positive edge triggering
• Differential output configuration providing both inverting and non-inverting signals
• Low power consumption suitable for battery-operated systems
• TTL-compatible input thresholds for mixed voltage interfacing

Flip Flops Applications

• Data storage and register circuits in portable electronics
• Timing control and synchronization in communication modules
• State machine implementation in embedded controllers
• Memory buffer interfaces in low-voltage digital systems

Flip Flops Procurement Notes

Verify the specific ordering suffix DR2G against the manufacturer's official datasheet to confirm the SOIC-14 package type and tape-and-reel packaging format. Ensure that the component meets RoHS compliance requirements as specified in the product documentation. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Flip Flops Selection Notes

Select this component when a dual D-type flip-flop is required for 2V to 3.6V logic systems. The 14-SOIC package is suitable for surface-mount assembly processes. Consider the 8 ns propagation delay and 24 mA drive capability for signal integrity in moderate-speed digital designs. Verify thermal performance within the -40°C to +85°C range for the intended application environment.

Flip Flops Part Context

This part belongs to the 74LCX series, which provides low-voltage operation compatible with 3.3V systems while maintaining TTL input compatibility. The MC74LCX74 variant specifically offers two independent D-type flip-flops per package, distinguishing it from single-element or octal configurations within the same logic family.
