MC74LCX244DTR2G

Overview

The MC74LCX244DTR2G is a low-voltage CMOS octal buffer and line driver manufactured by onsemi. It features non-inverting logic with three-state outputs, operating within a supply voltage range of 2 V to 3.6 V. The device provides high drive capability with output currents of ±24 mA. Propagation delays are specified at 9 ns for 3.3 V operation and 7 ns for 5 V operation. It is housed in a TSSOP-20 surface-mount package and supports an industrial temperature range from -40°C to +85°C.

Feature Summary

• Low-voltage CMOS technology optimized for 2 V to 3.6 V power supplies
• Octal configuration with three-state outputs for bus-oriented applications
• High drive strength supporting ±24 mA output current capability

Applications

• Memory module data buffering
• Clock distribution networks
• Bus-oriented architecture drivers

Procurement Notes

Verify the specific suffix DTR2G confirms the TSSOP-20 package and reel packaging format. Confirm RoHS compliance status through official datasheets or manufacturer documentation before integration. Ensure input voltage levels match the 2 V to 3.6 V operational range to prevent latch-up or damage during system design validation.

Selection Notes

Select this component when designing systems requiring octal buffering with low voltage operation between 2 V and 3.6 V. The three-state output allows multiple devices to share a common bus without interference. Consider the propagation delay specifications relative to system timing requirements and ensure the thermal performance meets the application's power dissipation constraints within the specified temperature range.

Part Context

This part belongs to the MC74LCX series of low-voltage CMOS logic devices from onsemi. The LCX family is designed for compatibility with standard 5 V TTL inputs while operating at lower voltages, making it suitable for mixed-voltage systems. The octal buffer configuration provides eight independent channels for signal conditioning and driving loads in digital circuits.

Replacement Considerations

Check for direct pin-compatible alternatives within the same LCX family or other manufacturers' low-voltage octal buffers. Verify that substitute parts maintain identical voltage ranges, drive strengths, and package dimensions to ensure seamless integration without circuit board modifications.
