CD74HC366E

Overview

The CD74HC366E is a high-speed CMOS logic hex buffer and line driver manufactured by Texas Instruments. It features six inverting channels with three-state outputs, designed for operation within a supply voltage range of 2 V to 6 V. The device is housed in a 16-pin PDIP package and supports an operating temperature range from -55°C to +125°C. Propagation delay varies with voltage, specified at 110 ns at 2 V, 22 ns at 4.5 V, and 19 ns at 6 V. It provides a maximum low-level output current of 7.8 mA.

Feature Summary

• Hex-channel configuration providing six independent inverting buffers
• Three-state output capability for bus-oriented applications
• Wide supply voltage operation supporting 2 V to 6 V ranges
• Extended industrial temperature rating for harsh environments

Applications

• Bus-oriented systems requiring signal inversion and isolation
• Clock buffering and distribution networks
• Memory address decoding circuits
• I/O port expansion interfaces

Procurement Notes

Verify the specific ordering suffix 'E' confirms the 16-pin PDIP package variant. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the selected component matches the required propagation delay specifications for your target supply voltage. Validate that the package type aligns with your PCB footprint requirements.

Selection Notes

Select this component when six inverted buffered signals with tri-state control are required. Consider the HC series compatibility with standard CMOS logic families. Evaluate the 2 V to 6 V operating range against system power constraints. Compare propagation delays at specific voltages against timing requirements. Verify thermal performance meets ambient conditions for industrial applications.

Part Context

This part belongs to the Texas Instruments 74HC family of high-speed CMOS logic devices. The 74HC series offers improved speed over legacy 74HCT counterparts while maintaining CMOS power efficiency. The CD74 prefix indicates commercial grade temperature variants within the broader logic portfolio. This specific model focuses on hex buffering with inversion capabilities.

Replacement Considerations

Compatible substitutes include other hex inverters with three-state outputs from the same logic family. Verify pinout compatibility before substitution. Check voltage ranges and propagation delays to ensure functional equivalence. Consult official cross-reference lists for validated alternative part numbers.
