MC74LCX574DWR2G

Flip Flops Overview

The MC74LCX574DWR2G is a low-voltage CMOS octal D-type flip-flop manufactured by onsemi. It operates within a supply voltage range of 2.3 V to 3.6 V and features five-volt tolerant inputs and outputs, enabling safe interfacing with 5.0 V devices. The device provides balanced output sink and source capabilities of 24 mA. It includes an IOFF specification that guarantees high-impedance states when the supply voltage is zero, supporting live insertion and withdrawal applications. The component is housed in a 20-SOIC surface-mount package.

Flip Flops Feature Summary

• Features five-volt tolerant inputs and outputs for direct interface with 5 V TTL logic
• Includes IOFF specification to guarantee high impedance when VCC equals zero volts
• Supports live insertion and withdrawal operations without system damage

Flip Flops Applications

• Interfacing between low-voltage logic circuits and 5 V TTL systems
• Data storage and buffering in portable electronic devices
• Memory address latching in battery-powered equipment

Flip Flops Procurement Notes

Verify RoHS compliance status through official manufacturer documentation prior to procurement. Confirm the specific suffix designation matches project requirements. Check current production status as components may be subject to discontinuation notices. Ensure the supplier provides valid traceability documents. Validate that the package type aligns with PCB footprint specifications.

Flip Flops Selection Notes

Select this component when a low-voltage octal D-type flip-flop with five-volt tolerance is required. It is suitable for designs needing 24 mA drive capability at voltages between 2.3 V and 3.6 V. Consider the IOFF feature if live insertion support is necessary. Compare against other LCX series variants for pinout or speed differences. Ensure the operating temperature range meets environmental constraints.

Flip Flops Part Context

This part belongs to the MC74LCX574 family of low-voltage CMOS octal D-type flip-flops. It shares functional similarities with other members like the MC74LCX574DW but differs in packaging and compliance markings.
