CD74HC368M

Overview

The CD74HC368M is a high-speed CMOS logic hex buffer and line driver manufactured by Texas Instruments. It features six independent buffers with three-state outputs, combining non-inverting and inverting configurations within a single package. The device operates on a supply voltage range of 2V to 6V. Key electrical parameters include a maximum static current of 8µA and output drive capabilities of -6mA for high-level and 6mA for low-level states. Propagation delay is typically 24ns at a nominal voltage of 6V. It is housed in a 16-pin SOIC package and supports surface-mount installation.

Feature Summary

• Integrates six independent buffer channels with mixed non-inverting and inverting polarities
• Provides three-state output control for bus-oriented applications
• Supports wide supply voltage operation from 2V to 6V
• Designed for high-speed CMOS logic performance

Applications

• Bus-oriented systems requiring signal buffering
• Clock distribution circuits
• Memory address decoding
• Signal isolation between digital blocks

Procurement Notes

Verify the specific suffix 'M' corresponds to the SOIC-16 narrow package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the component meets the required operating temperature range specifications for the intended application environment.

Selection Notes

Select this component when a combination of both non-inverting and inverting buffers is required in a single package. It serves as a suitable alternative to separate buffer ICs, reducing board space. Consider the HC series speed and voltage characteristics against HCT requirements if TTL compatibility is needed.

Part Context

This part belongs to the Texas Instruments CD74HC36x family of high-speed CMOS logic devices. It is functionally related to the CD74HC367, which offers exclusively non-inverting buffers. Both share similar pinouts and electrical characteristics but differ in output polarity configuration, allowing designers to choose based on signal inversion needs.

Replacement Considerations

Direct substitutes include CD74HC368MT and CD74HC368M96 from Texas Instruments. Cross-manufacturer equivalents such as SN74HC368DR (Texas Instruments) or 74HC368D (Nexperia) may be considered if pinout and electrical specifications match exactly.
