MC74LCX74DT

Flip Flops Overview

The MC74LCX74DT is a dual D-type flip-flop from the onsemi 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 single-ended inputs. The device provides inverting and non-inverting polarities, supporting surface-mount installation in a TSSOP-14 package. Key electrical characteristics include a propagation delay of 8 ns, 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 edge-triggered flip-flops integrated into a single compact package

Flip Flops Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives by checking the material declaration. Confirm availability status directly with authorized distributors as lead times may vary based on production cycles and regional stock levels.

Flip Flops Selection Notes

Select this component when designing low-power digital circuits requiring dual flip-flops within a minimal footprint. Consider the 2 V to 3.6 V operating range for compatibility with modern low-voltage microcontrollers. Evaluate the 8 ns propagation delay against system timing requirements to ensure adequate setup and hold times are met during high-frequency operation.

Flip Flops Part Context

This part belongs to the 74LCX series, characterized by ultra-low power consumption and high-speed performance compared to standard 74HC devices. The LCX family is optimized for battery-powered applications and portable electronics where energy efficiency is critical. It maintains pinout compatibility with legacy 74-series logic while offering improved electrical characteristics.

Flip Flops Replacement Considerations

Direct substitutes include MC74LCX74DTR2G and MC74LCX74MTCX. Verify that alternative packages match the required PCB layout constraints. Ensure functional equivalence regarding propagation delay and output drive current before finalizing any cross-reference selection.
