MC74LCX244DWG

Overview

The MC74LCX244DWG is an octal buffer and line driver manufactured by onsemi. It operates within a supply voltage range of 1.65V to 3.6V. The device features eight non-inverting channels with three-state outputs. It provides high impedance TTL-compatible inputs and outputs tolerant to 5V levels. Key electrical specifications include a maximum output current of 24mA and a static power supply current of 10μA. The component supports an operating temperature range from -40°C to +85°C and is housed in a 20-pin SOIC surface-mount package.

Feature Summary

• Provides five-volt tolerant inputs and outputs for safe interfacing with 5V devices
• Features low static power consumption across all logic states
• Supports hot swapping capabilities for system maintenance

Applications

• Memory address driving
• TTL level bus-oriented transceiver applications
• High-impedance state data bus management

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape-and-reel options. Ensure compatibility with 5V tolerant input requirements for your target interface. Confirm RoHS compliance status and lead-free manufacturing details directly with the manufacturer or authorized distributors before finalizing procurement orders.

Selection Notes

Select this component when interfacing low-voltage CMOS logic with 5V TTL systems. It is suitable for designs requiring low static power dissipation and high noise immunity. Consider the 20-pin SOIC package constraints for PCB layout. Verify that the 1.65V to 3.6V supply range aligns with your system's power architecture.

Part Context

This part belongs to the LCX series of low-voltage CMOS logic devices from onsemi. It functions as an octal buffer designed for high-speed data transmission. The series emphasizes compatibility with standard TTL logic levels while operating at reduced supply voltages. It serves as a bridge between different voltage domains in digital circuit designs.

Replacement Considerations

Check for direct pin-to-pin replacements within the same logic family. Verify equivalent voltage tolerance and drive strength specifications. Ensure the alternative component supports the required 5V input tolerance and three-state output functionality for seamless integration.
