MC74LCX574M

Flip Flops Overview

The MC74LCX574M 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 direct interfacing with 5.0 V devices. The device provides three-state non-inverting outputs with balanced sink and source capabilities of 24 mA. It exhibits near-zero static supply current across all logic states, significantly reducing system power requirements. The component supports live insertion and withdrawal operations and includes an IOFF specification to guarantee high impedance when the supply voltage is zero.

Flip Flops Procurement Notes

Verify that the specific part number matches the required package type and suffix codes for automotive or industrial qualification if applicable. Confirm RoHS compliance status through official documentation. Ensure input voltage levels do not exceed the specified tolerance limits during operation. Check for alternative packages if surface-mount constraints exist. Validate supply voltage ranges against system design requirements before integration.

Flip Flops Selection Notes

Select this component when designing systems requiring interface between 2.3 V to 3.6 V logic and 5.0 V environments. Consider its low static current consumption for power-sensitive applications. Evaluate the need for three-state outputs for bus sharing scenarios. Assess thermal management requirements based on operating temperature ranges. Compare propagation delays against system timing constraints to ensure signal integrity.

Flip Flops Part Context

This component belongs to the 74LCX series of low-voltage CMOS logic devices from onsemi. It is functionally similar to other octal D-type flip-flops but optimized for lower voltage operation compared to standard 5 V logic families. The device serves as a bridge between different voltage domains in mixed-signal designs. Its pinout compatibility with legacy 74-series components facilitates easier migration in existing circuit layouts.

Flip Flops Replacement Considerations

Direct substitutes include MC74LCX574DWR2G and MC74LCX574MWX. Verify package compatibility and electrical specifications before substitution. Cross-reference with equivalent parts from other manufacturers ensuring matching voltage tolerances and output drive capabilities.
