Overview
The MC74LCX574DW is a low-voltage CMOS octal D-type flip-flop manufactured by onsemi. It operates from a 2.3 V to 3.6 V supply and features 5 V-tolerant inputs and outputs. The device provides non-inverting, three-state outputs with balanced sink and source capabilities of 24 mA. It supports live insertion and withdrawal and includes an IOFF specification for high impedance when VCC is 0 V. The component is designed for LVTTL and LVCMOS compatibility, ensuring near-zero static supply current across all logic states.
Feature Summary
- Features 5 V tolerant inputs and outputs for safe interfacing with 5.0 V devices
- Supports live insertion and withdrawal operations
- Provides balanced 24 mA output drive capability in both sink and source modes
- Includes IOFF specification to guarantee high impedance state when VCC equals 0 V
Applications
- Interface between 5 V TTL logic and low-voltage CMOS systems
- Data storage applications requiring live insertion support
- Systems demanding reduced switching noise performance
- Low-power designs utilizing LVTTL or LVCMOS compatible interfaces
Procurement Notes
Verify the specific suffix against the manufacturer datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status as required by project regulations. Check for automotive qualification requirements if the application demands AEC-Q100 standards. Ensure voltage tolerance levels match the system interface requirements before procurement.
Selection Notes
Select this component for applications requiring 5 V tolerance within a low-voltage operating range. Consider the balanced output drive strength for driving moderate loads. Evaluate the live insertion capability if hot-swapping is necessary. Verify that the supply voltage range aligns with the system power rails.
Part Context
This part belongs to the LCX series of low-voltage CMOS logic devices. It serves as an octal D-type flip-flop variant within the broader family of high-performance logic components. The series is characterized by its ability to operate at lower voltages while maintaining compatibility with higher voltage logic families through specific input/output design.
Replacement Considerations
Direct substitutes include MC74LCX574DWR2G and MC74LCX574MTCX. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive strength. Ensure the replacement part meets the same 5 V tolerance and supply voltage requirements.
