M74HC366RM13TR

Overview

The M74HC366RM13TR is a high-speed CMOS hex bus buffer with inverting outputs and three-state capabilities, manufactured by STMicroelectronics. It utilizes silicon gate C2MOS technology for advanced performance. The device operates within a supply voltage range of 2V to 6V and features symmetrical output impedance with minimum drive currents of 6mA. Propagation delay is typically 10ns at 6V. It includes dual enable inputs (G1 and G2) that control the output state, ensuring high-impedance states under specific logic conditions.

Feature Summary

• Hex bus buffer configuration with six independent inverting channels
• Three-state outputs controlled by dual active-low enable inputs
• High noise immunity with defined input thresholds relative to supply voltage
• Built-in protection circuits against static discharge and transient excess voltage

Applications

• Bus-oriented memory and register implementations
• Clock drivers and buffered clock distribution
• Line drivers for data transmission interfaces
• Carry propagation in arithmetic logic units

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm the datasheet revision matches the production batch. Check RoHS compliance status as indicated on official documentation. Ensure storage and handling procedures meet moisture sensitivity level requirements to prevent package damage prior to soldering.

Selection Notes

Select this component when designing systems requiring inverted buffering with tri-state control. Verify that the operating voltage range aligns with the system power rails. Consider the propagation delay specifications for timing-critical applications. Ensure the package type matches the PCB footprint constraints and thermal management requirements of the assembly process.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It is functionally compatible with standard 74LS366 equivalents but offers improved speed and lower power consumption. The RM13 suffix indicates surface-mount packaging in a tape and reel format suitable for automated assembly processes.

Replacement Considerations

Direct substitutes include other manufacturers' 74HC366 variants such as SN74HC366 from Texas Instruments or MC74HC366 from ON Semiconductor. Verify pin compatibility and electrical characteristics before substitution.
