MC74LCX574DT

Flip Flops Overview

The MC74LCX574DT is a low-voltage CMOS octal D-type flip-flop manufactured by onsemi. It operates within a supply voltage range of 2 V to 3.6 V and features 5 V-tolerant inputs and outputs, enabling safe interfacing with 5.0 V devices. The component provides single-ended, non-inverting outputs with a balanced sink and source current capability of 24 mA. Packaged in a TSSOP-20 surface-mount format, it exhibits a propagation delay of 9.5 ns and supports an operating temperature range from -40 °C to +85 °C.

Flip Flops Feature Summary

• Features 5 V tolerant input and output interfaces for compatibility with 5.0 V logic systems
• Provides high impedance state when VCC is zero via IOFF specification
• Delivers balanced 24 mA output drive capability for improved switching noise performance

Flip Flops Applications

• Interface between 5 V TTL logic and low-voltage CMOS circuits
• Data storage and buffering in portable electronic devices
• General-purpose octal register applications in consumer electronics

Flip Flops Procurement Notes

Verify the specific package variant and suffix against official datasheets, as distribution channels may list obsolete or superseded part numbers. Confirm RoHS compliance status and material composition details directly with the manufacturer or authorized distributors prior to procurement. Ensure that the selected component matches the required thermal and electrical specifications for the intended application environment.

Flip Flops Selection Notes

Select this component for designs requiring interface between 5 V and 2.3–3.6 V logic domains. The 5 V tolerance allows direct connection to higher voltage sources without level shifting. Consider the TSSOP-20 package for space-constrained surface mount applications. Verify that the 24 mA output drive meets the load requirements of the destination circuitry.

Flip Flops Part Context

This device belongs to the 74LCX series of low-voltage CMOS logic integrated circuits. The series is characterized by high speed and low power consumption, making it suitable for battery-operated systems. The octal configuration provides eight independent D-type flip-flops with positive edge triggering within a single package.
