MC74LCX574DTG

Flip Flops Overview

The MC74LCX574DTG is a low-voltage CMOS octal D-type flip-flop manufactured by onsemi. It operates within a supply voltage range of 2V to 3.6V and features five-volt tolerant inputs and outputs, enabling safe interfacing with 5.0V devices. The device provides three-state, non-inverting outputs with balanced sink and source capabilities of 24mA. It exhibits a maximum propagation delay of 8.5ns at 3.3V with a 50pF load and supports clock frequencies up to 150MHz. Packaged in a 20-pin TSSOP, it ensures high impedance when VCC is 0V via the IOFF specification.

Flip Flops Feature Summary

• Features five-volt tolerant inputs and outputs for direct interface with 5V TTL logic systems.
• Provides balanced 24mA output drive capability for improved switching noise performance.
• Includes IOFF specification to guarantee high-impedance state when power is removed.
• Supports live insertion and withdrawal operations without system damage.

Flip Flops Applications

• High-performance digital data storage applications
• Interface bridging between 5V and low-voltage logic domains
• Portable battery-powered electronic equipment

Flip Flops Procurement Notes

Verify the specific suffix 'DTG' against the manufacturer's current datasheet to confirm package type and automotive qualification status. Ensure compatibility with RoHS and halogen-free requirements if mandated by project specifications. Cross-reference lead times and availability directly with authorized distributors, as component status may vary by region and production batch.

Flip Flops Selection Notes

Select this component for designs requiring robust 5V tolerance alongside low-voltage operation. The 24mA drive strength suits moderate capacitive loads. Verify that the 8.5ns propagation delay meets timing constraints. Consider the 20-TSSOP package dimensions for PCB layout. Confirm AEC-Q100 qualification if the application demands automotive-grade reliability standards.

Flip Flops Part Context

This part belongs to the LCX logic family, designed for low-voltage CMOS applications. It serves as an octal D-type flip-flop alternative to higher-voltage counterparts. The series emphasizes low static power consumption and high-speed performance suitable for modern portable electronics and communication interfaces requiring mixed-voltage signal translation.
