MC74HCT366ADTR2G

Overview

The MC74HCT366ADTR2G is a high-performance silicon-gate CMOS hex inverting buffer with three-state outputs manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 6.0 V and features two common active-low output enables that place outputs into a high-impedance state when asserted high. The device inputs are compatible with standard CMOS or LSTTL outputs, providing an output drive capability equivalent to 15 LSTTL loads. It contains 90 FETs (22.5 equivalent gates) and supports operating temperatures from -55°C to +125°C.

Feature Summary

• Hex inverting buffer architecture with three-state outputs controlled by two common active-low enables
• LSTTL-compatible inputs allowing direct interfacing with standard CMOS or LSTTL outputs
• High noise immunity characteristic inherent to CMOS devices
• Pb-free package construction compliant with JEDEC standards

Applications

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

Procurement Notes

Verify the specific suffix 'DTR2G' corresponds to the TSSOP-16 package and tape & reel shipping configuration. Confirm RoHS compliance status and ensure the ordering quantity aligns with the standard factory pack size of 2500 units per reel. Check for any automotive-specific '-Q' variants if unique site control requirements apply.

Selection Notes

Select this component when a hex inverting buffer with tri-state functionality is required for bus applications. Ensure the system logic levels match the HCT series compatibility with LSTTL inputs. Verify that the power supply voltage remains within the 2.0 V to 6.0 V operational range to maintain specified propagation delays and output drive capabilities.

Part Context

This part belongs to the MC74HCT366A family of high-speed silicon-gate CMOS logic devices. It shares identical pinouts with LS366 equivalents, facilitating drop-in replacements in legacy designs. The device is designed for high-speed digital applications requiring low input current and robust noise immunity while maintaining compatibility with TTL-driven systems.
