MC74LCX16244DT

Overview

The MC74LCX16244DT is a low-voltage CMOS octal buffer and line driver manufactured by onsemi. It features five-volt tolerant inputs and outputs, allowing for direct interfacing between 3.3V logic systems and 5V peripherals without level shifting components. The device provides non-inverting signal transmission with three-state output control, enabling efficient bus management in high-density digital applications.

Feature Summary

• Provides eight-channel non-inverting buffering with independent output enable controls
• Supports direct interface between 3.3V and 5V logic domains via voltage-tolerant I/O structures
• Features three-state outputs to facilitate safe parallel data bus connections

Applications

• High-density memory modules requiring bidirectional data buffering
• Clock distribution networks for multi-drop system architectures
• Bus-oriented transceivers connecting microprocessors to peripheral devices

Procurement Notes

Verify the specific suffix 'DT' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering code with official distributor catalogs to confirm availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when designing systems that require robust interfacing between 3.3V and 5V logic families. The low-voltage CMOS technology ensures minimal power consumption while maintaining high-speed performance. Consider the package constraints and thermal characteristics relative to your PCB layout requirements.

Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices from onsemi. The LCX family is designed to replace older HC/HCT technologies in modern low-power applications. It offers improved switching speeds and lower static power dissipation compared to standard CMOS counterparts, making it suitable for battery-operated and portable electronic equipment.

Replacement Considerations

Check for pin-compatible alternatives within the same 74LCX family or cross-brand equivalents like NXP's LVC series. Verify that substitute parts maintain identical voltage tolerance levels and propagation delay characteristics to ensure circuit compatibility.
