CD74HCT368MT

Overview

The CD74HCT368MT is a high-speed CMOS logic hex buffer and line driver manufactured by Texas Instruments. It features six independent inverting buffers with three-state outputs, operating within a supply voltage range of 4.5 V to 5.5 V. The device utilizes the HCT logic series for compatibility with TTL inputs. Key electrical parameters include a propagation delay of 30 ns at 4.5 V, a static current of 8 uA, and output drive capabilities of -4 mA (high) and 4 mA (low). It operates reliably across an extended temperature range from -55°C to +125°C and is housed in a 16-pin SOIC narrow package.

Feature Summary

• Integrates six independent inverting buffer channels with three-state output control for flexible bus interfacing.
• Utilizes high-speed CMOS technology combined with HCT input structures to ensure direct compatibility with standard TTL logic levels.
• Provides robust signal buffering and line driving capabilities suitable for high-frequency digital applications.

Applications

• Bus-oriented memory and address drivers
• Clock distribution circuits
• Data register drives

Procurement Notes

Verify the specific suffix 'M96' or 'MT' against the manufacturer's latest datasheet to confirm package dimensions and reel specifications. Ensure the ordered component matches the required HCT logic family and three-state functionality. Cross-reference the RoHS compliance status and lead times directly with authorized distributors or Texas Instruments official channels prior to procurement.

Selection Notes

Select this component when designing systems requiring six-channel inverting buffering with three-state isolation. It is appropriate for applications needing direct interface between CMOS and TTL logic families due to its HCT input structure. Consider the SOIC-16 package for surface-mount assembly constraints and verify that the 4.5 V to 5.5 V supply voltage aligns with the system power architecture.

Part Context

This part belongs to the CD74HCT368 series of high-speed CMOS logic devices. It serves as the inverting counterpart to the non-inverting CD74HC367. The series is designed for general-purpose digital logic applications, offering improved switching speeds compared to standard HC logic while maintaining low power consumption. It is widely used in computing and industrial control systems.

Replacement Considerations

Compatible substitutes include CD74HCT368E (PDIP package) and CD74HCT368M (standard SOIC package). Verify pinout compatibility and electrical characteristics before substitution.
