74LCX574MTC

Overview

The onsemi 74LCX574MTC is a low-voltage CMOS octal D-type flip-flop housed in a 20-TSSOP package. It operates within a supply voltage range of 2 V to 3.6 V and features single-ended inputs with single-ended outputs. The device provides non-inverting logic polarity and supports surface-mount installation. Key electrical specifications include a propagation delay of 9.5 ns, high-level output current of -24 mA, and low-level output current of 24 mA. It functions reliably across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Octal D-type edge-triggered flip-flop architecture for parallel data storage
• 5 V tolerant input and output interface capability for mixed-voltage systems
• High impedance state guarantee when supply voltage is zero

Applications

• Parallel data buffering in digital communication interfaces
• Register stages in microprocessor-based control systems
• Data acquisition system input/output staging

Procurement Notes

Verify component authenticity through authorized distribution channels due to end-of-life status. Confirm RoHS compliance documentation matches the specific manufacturing lot. Validate that the TSSOP-20 footprint aligns with existing PCB designs. Ensure thermal management strategies account for the specified operating temperature limits during system integration.

Selection Notes

Select this component for applications requiring octal data latching with 5 V tolerance at low voltages. Compare against HC series for speed requirements and LVC series for lower power consumption. Verify that the 20-TSSOP package dimensions fit the mechanical constraints. Check if differential output variants are needed for noise-sensitive environments.

Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices. It serves as an octal variant within the broader 74-series logic portfolio. The device complements other LCX components like the dual flip-flop 74LCX74 by providing higher density data storage capabilities in a compact surface-mount form factor.
