Overview
The MC74HC240AFL2 is an octal buffer and line driver from the HC logic series, manufactured by onsemi. It features eight inverting inputs with three-state outputs housed in a 20-SOIC package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a high-level output current of -7.8 mA and a low-level output current of 7.8 mA. Static current is specified at 4 µA, while operating supply current reaches 160 µA. The component supports a maximum power dissipation of 450 mW and functions across a temperature range of -55 °C to +125 °C.
Feature Summary
- Provides octal buffering with inverting polarity for signal integrity
- Features three-state outputs to facilitate bus-oriented systems
- Operates reliably across extended industrial temperature ranges
Applications
- Bus-oriented systems requiring signal isolation
- Memory address decoding circuits
- Clock distribution networks
Procurement Notes
Verify the specific suffix 'FL2' against official datasheets to confirm package dimensions and tape/reel specifications. Ensure compatibility with existing PCB footprints for the 20-SOIC form factor. Confirm RoHS compliance status through manufacturer declarations prior to integration into regulated assemblies.
Selection Notes
Select this component when extended temperature operation down to -55 °C is required, distinguishing it from commercial grade variants. The HC series offers standard CMOS performance suitable for general-purpose digital applications. Consider the 20-SOIC package constraints regarding board space and thermal management capabilities during layout design.
Part Context
This part belongs to the MC74HC240A family of octal buffers. It shares functional similarities with other SOIC-20 variants like the MC74HC240ADWR2G but differs in packaging style. The FL2 designation typically indicates a specific bulk or tube packaging option compared to reel-based counterparts.
Replacement Considerations
Direct substitutes include MC74HC240ADWR2G and MC74HC240ADTR2G. Verify pinout compatibility and ensure the replacement package matches the 20-SOIC footprint requirements.
