CD74HCT368M

Overview

The CD74HCT368M is a high-speed CMOS logic hex buffer and line driver manufactured by Texas Instruments. It features six inverting buffers with three-state outputs, designed for bus-oriented systems. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a maximum 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 is housed in a 16-pin SOIC-Narrow package and supports surface mount installation.

Feature Summary

• Provides six independent inverting buffer channels with three-state output control
• Compatible with standard TTL voltage levels through HCT logic family design
• Supports high-speed data transmission with low propagation delay characteristics

Applications

• Bus-oriented memory and address decoding systems
• Clock drivers and timing circuits requiring signal inversion
• Data routing applications involving bidirectional data flow management

Procurement Notes

Verify the specific suffix against the manufacturer's latest datasheet to confirm pinout compatibility and electrical specifications. Ensure the component matches the required operating temperature range and packaging type for your assembly process. Cross-reference the ordering information with official Texas Instruments documentation to avoid counterfeit parts.

Selection Notes

Select this component when designing systems that require buffered inverting signals with tri-state capability. It is suitable for interfaces between different logic families due to its HCT compatibility. Consider the package constraints and thermal requirements when integrating into dense PCB layouts.

Part Context

This part belongs to the CD74HCT series of high-speed CMOS logic devices from Texas Instruments. It shares functional similarities with other hex buffer variants like the CD74HC368 but offers TTL-compatible input thresholds. The series is widely used in digital electronics for signal conditioning and bus isolation.

Replacement Considerations

Check for direct substitutes such as CD74HCT368MT or CD74HCT368M96 which share identical logical functions. Verify pin-to-pin compatibility before replacing to ensure seamless integration without circuit redesign.
