MC74F367N

Overview

The MC74F367N is a hex bus driver belonging to the F/FAST logic series, manufactured by onsemi. It features six independent non-inverting buffers with three-state outputs housed in a 16-pin plastic small outline package (SOIC-16). The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include a maximum propagation delay of 5.5ns at 5V with 50pF load capacitance, an output high current of 15mA, and an output low current of 64mA.

Feature Summary

• Provides six independent non-inverting buffer channels for signal driving
• Features three-state outputs allowing bus line sharing and isolation
• Organized as a single 6-bit path or split into 2-bit and 4-bit sections
• Designed for high-speed operation compatible with TTL unit loads

Applications

• Clock driver circuits requiring high-speed signal buffering
• Three-state memory address drivers for data buses
• Bus-oriented receivers and transmitters in digital systems
• General-purpose hex bus drivers for parallel data transmission

Procurement Notes

Verify the specific suffix 'N' against the manufacturer's official datasheet to confirm the exact package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements if mandated by your design standards. Cross-reference the ordering code with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when high-speed switching performance is required alongside three-state bus control capabilities. The F/FAST series offers faster propagation delays compared to standard HC or LS logic families. Consider the 64mA low-level output current for driving heavier capacitive loads or multiple unit loads on shared bus lines without external buffering.

Part Context

This part belongs to the 74F logic family, known for high-speed performance using Schottky clamped diodes to prevent saturation. The MC74F367N serves as a hex buffer, distinct from the SN74HC367N which utilizes CMOS technology for lower power consumption but potentially different speed characteristics. It is functionally similar to other 74F367 variants from manufacturers like Motorola or NXP.

Replacement Considerations

Direct substitutes include the SN74F367 from Texas Instruments or the MC74F367DR2 from onsemi in SOIC packaging. Verify pin compatibility and electrical parameters such as propagation delay and output current when replacing with equivalents from other vendors.
