MC74F368N

Overview

The MC74F368N is a hex bus driver from the F/FAST series by onsemi, designed for digital signal distribution. It features six non-inverting buffers with single-ended inputs and outputs. The device operates within a supply voltage range of 2.0 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 15 ns at 5 V with 50 pF load, high output drive capability of 24 mA, and low input leakage current. It is housed in a 20-pin DIP package suitable for through-hole mounting.

Feature Summary

• Hex configuration providing six independent non-inverting buffer channels
• High-speed F/FAST technology optimized for rapid signal propagation
• Robust output drive capability supporting direct interface to loads
• Single-ended input and output architecture for standard logic interfacing

Applications

• Address bus drivers in microprocessor systems
• Clock buffer distribution networks
• Memory data line buffering
• General-purpose digital signal routing

Procurement Notes

Verify the package type matches design requirements, as N suffix indicates DIP. Confirm RoHS compliance status via official datasheet or component declaration, as historical batches may vary. Ensure operating voltage aligns with system 5V logic levels. Check for obsolescence notices given the age of the F-series family. Validate pinout compatibility if replacing legacy components.

Selection Notes

Select this component when high-speed buffering of multiple parallel lines is required. The F-series offers faster switching than standard LS counterparts. Consider power consumption trade-offs compared to HC/HCT families. Verify thermal dissipation capabilities for the DIP package in enclosed environments. Ensure input voltage levels are compatible with upstream logic sources.

Part Context

Part of onsemi's extensive 74F logic portfolio, the MC74F368N serves as a high-performance alternative to slower TTL equivalents. The F/FAST series was engineered to bridge the speed gap between standard logic and ECL technologies while maintaining CMOS compatibility. This specific part number represents the industry-standard hex buffer configuration widely used in legacy and industrial digital designs.

Replacement Considerations

MC74F368DR2G (SOIC-20 surface mount equivalent). MC74F368MTC (TSSOP-20 surface mount equivalent). SN74F368N (Texas Instruments DIP equivalent). Verify pinout and electrical specifications match before substitution.
