MC74F245M

Overview

The MC74F245M is an octal bus transceiver with three-state outputs and a direction control input. It facilitates bidirectional data transmission between two buses. The device features a low output impedance designed to improve timing accuracy and reduce signal distortion. It operates within a specified voltage range and supports standard logic levels. The component is housed in a small outline package suitable for surface mount applications.

Feature Summary

• Octal configuration enables simultaneous eight-bit data transfer
• Bidirectional capability allows flexible bus architecture design
• Three-state outputs isolate the bus when disabled

Applications

• Memory mapping systems
• Clock drivers
• Bus-oriented architectures

Procurement Notes

Verify the specific suffix 'M' indicates the tape and reel packaging option rather than a functional difference from the standard variant. Confirm the manufacturer datasheet for the exact operating temperature range and electrical characteristics applicable to this specific marking code before finalizing procurement specifications.

Selection Notes

Select this component when an octal wide bus interface is required with bidirectional flow control. Ensure the system voltage matches the device's rated supply range. Consider the package type compatibility with the printed circuit board layout and assembly process requirements.

Part Context

This part belongs to the Fairchild Semiconductor onsemi 74F series of high-speed CMOS logic devices. The 74F245 is a widely used standard logic component for general-purpose data bus applications. It provides a balance of speed and power consumption typical of the F series technology.

Replacement Considerations

Compatible substitutes include the SN74F245N or equivalent octal bus transceivers from other manufacturers. Verify pinout compatibility and electrical parameters such as propagation delay and drive current before substitution.
