MC74LVX244DWR2G

Overview

The MC74LVX244DWR2G is an octal buffer and line driver manufactured by onsemi, belonging to the LVX logic series. It features eight non-inverting inputs and outputs housed in a 20-SOIC package. The device operates within a supply voltage range of 2 V to 3.6 V. Key electrical parameters include a propagation delay of 18 ns at 2.7 V and 12.8 ns at 3.3 V. Output drive capabilities are specified with a low-level output current of 32 mA and a high-level output current of -4 mA. Static current consumption is 4 uA, while maximum power supply current is also 4 uA. The component supports surface mount installation and functions reliably across an operating temperature range from -40 C to +85 C.

Feature Summary

• Provides octal buffering for signal integrity in low-voltage digital systems
• Features three-state outputs for bus-oriented memory and circuit control applications
• Operates efficiently with ultra-low static power consumption

Applications

• Bus-oriented memory and circuit control
• Clock drivers
• Buffering for microprocessor systems

Procurement Notes

Verify the specific ordering suffix DWR2G to confirm the SOIC-20 wide package and tape-and-reel packaging configuration. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles required for surface-mount assembly processes. Confirm that the LVX logic family voltage specifications align with the target system's I/O requirements before finalizing procurement.

Selection Notes

Select this component when designing systems requiring octal buffering with low-voltage operation between 2 V and 3.6 V. It is suitable for applications needing moderate drive strength with low power dissipation. Consider the propagation delay characteristics relative to system clock speeds. Verify that the 20-SOIC package dimensions fit the available PCB footprint constraints.

Part Context

This part belongs to the MC74LVX244 series of octal buffers and line drivers. It utilizes silicon gate CMOS technology to achieve high-speed operation while maintaining low power consumption. The LVX series is designed for low-voltage applications, offering performance comparable to higher voltage families while operating at reduced supply voltages.

Replacement Considerations

Check for direct pin-compatible alternatives within the same LVX family or other manufacturers' octal buffer offerings. Ensure voltage ranges and drive currents match the original design specifications.
