MC74HC240AFL2-MO

Overview

The MC74HC240AFL2-MO is an octal buffer and line driver from the 74HC logic family, manufactured by Motorola. It features eight inverting inputs with three-state outputs, operating within a supply voltage range of 2 V to 6 V. The device utilizes a 20-SOIC surface-mount package. Key electrical specifications include a maximum propagation delay of 80 ns at 2 V and 14 ns at 6 V. It supports low-level output currents of 7.8 mA and high-level output currents of -7.8 mA, with a static current of 4 uA. The component operates reliably across a temperature range of -55°C to +125°C.

Procurement Notes

Verify the manufacturer designation on the datasheet, as this part number is associated with Motorola but may also be listed under NXP USA Inc. due to corporate acquisitions. Confirm the specific suffix 'L2' corresponds to the 20-SOIC package variant. Ensure RoHS compliance status matches your project requirements by checking the official product specification sheet before procurement.

Selection Notes

Select this component when an octal inverting buffer with three-state capability is required for high-speed digital applications. The HC logic family offers compatibility with standard CMOS levels while providing faster switching speeds than legacy 74LS series. Consider the 20-SOIC package constraints and the wide operating voltage range suitable for various digital logic interfaces.

Part Context

This component belongs to the 74HC240A series of octal buffers and line drivers. It is functionally equivalent to other manufacturers' parts like the SN74HC240. The 'A' suffix typically denotes improved specifications or updated manufacturing processes compared to earlier versions. It serves as a critical interface element in digital circuit design for managing data flow and signal integrity.

Replacement Considerations

Compatible substitutes include the MC74HC240ADWG from onsemi and generic equivalents such as the SN74HC240N. Verify pinout compatibility and electrical parameters against the original datasheet. Ensure the replacement part supports the same 20-SOIC package and operating temperature range.
