MC74F240MR1

Overview

The MC74F240MR1 is an octal bus driver manufactured by onsemi, belonging to the 74F logic family. It features eight non-inverting buffers with 3-state outputs, designed for high-speed digital signal distribution. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum low-level output current of 24 mA. It utilizes a 20-pin SOIC package and functions reliably across an industrial temperature range from -40 °C to +85 °C.

Feature Summary

• Provides eight non-inverting buffer channels for parallel data transmission
• Incorporates 3-state output capability to facilitate bus-oriented architectures
• Engineered for high-speed operation using the 74F logic technology

Applications

• Clock drivers and buffering in high-speed digital systems
• Bus-oriented memory and address drivers
• Control signal routing in telecommunications equipment

Procurement Notes

Verify the specific suffix MR1 indicates tape-and-reel packaging when sourcing components. Confirm the active status and RoHS compliance details directly with the manufacturer or authorized distributors prior to procurement. Ensure the ordering quantity matches the reel specifications required for your assembly process.

Selection Notes

Select this component for applications requiring high-speed switching and significant drive current capabilities. The 74F series offers faster propagation delays compared to standard TTL variants. Consider the 20-pin SOIC footprint for PCB layout compatibility and ensure the operating voltage aligns with the 5 V logic system requirements.

Part Context

This part is based on the industry-standard 74F240 architecture, widely recognized for its performance in legacy and modern digital designs. The MC74 prefix denotes onsemi's manufacturing variant, ensuring quality and reliability standards consistent with the original specification while providing supply chain diversification for electronic manufacturers.

Replacement Considerations

Compatible substitutes include the MC74F240DWR2G and MC74F240N. Verify pinout compatibility and electrical characteristics before substitution. Alternative packages such as SOIC-20 or DIP-20 may be used if mechanical constraints allow.
