MC74HCT366ADR2G

Overview

The MC74HCT366ADR2G is a high-performance silicon-gate CMOS hex inverting buffer with three-state outputs manufactured by onsemi. It features two common active-low output enables that place the outputs into a high-impedance state when asserted high. The device provides an operating voltage range of 2.0 to 6.0 V and includes LSTTL-compatible inputs, allowing direct interfacing with standard CMOS or LSTTL outputs. It supports a maximum propagation delay of 19 ns at 4.5 V and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Hex inverting buffer architecture with three-state outputs controlled by two common active-low enables
• LSTTL-compatible input logic levels ensuring compatibility with standard CMOS and LSTTL outputs
• High noise immunity characteristics inherent to CMOS technology
• Wide operating voltage range supporting 2.0 V to 6.0 V supply conditions

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmissions

Procurement Notes

Verify the specific package suffix (e.g., D for SOIC-16) matches the required footprint. Confirm RoHS compliance status and lead-free marking requirements. Ensure the ordering quantity aligns with tape and reel specifications provided in the manufacturer's documentation. Cross-reference the AEC-Q100 qualification if automotive application standards are mandatory.

Selection Notes

Select this component when a hex inverting buffer with tri-state capability is required. The HCT logic family ensures TTL compatibility while maintaining CMOS low power consumption. Verify that the input signal levels match the specified VIH and VIL thresholds for the target supply voltage. Consider the thermal resistance values if operating near maximum junction temperatures.

Part Context

This part belongs to the MC74HCT366A series of high-speed CMOS logic devices. It serves as a functional equivalent to the LS366 but utilizes modern silicon-gate CMOS technology for improved performance and lower power dissipation. The device is designed for general-purpose digital applications requiring buffered and inverted signals with bus-hold capabilities.
