MC74LVX244DWR2

Overview

The MC74LVX244DWR2 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 surface-mount package. The device operates within a supply voltage range of 2 V to 3.6 V, with a maximum power dissipation of 180 mW. Key electrical parameters include a static current of 4 uA and an operating supply current of 40 uA. Output drive capabilities are specified at -4 mA for high level and 4 mA for low level. Propagation delay is 14.9 ns at 2.7 V and 10.6 ns at 3.3 V. The component supports three-state outputs and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Provides octal buffering and line driving functionality with non-inverting signal paths.
• Supports low-voltage operation suitable for systems requiring 2 V to 3.6 V power supplies.
• Features three-state outputs to facilitate bus-oriented communications.
• Utilizes silicon gate CMOS technology for high-speed performance with low power consumption.

Applications

• Memory mapping control
• Clock buffering
• Bus-oriented architectures

Procurement Notes

Verify the exact suffix DWR2 against official datasheets to confirm tape-and-reel packaging and specific manufacturing lot details. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for obsolescence notices or lifecycle changes directly from onsemi before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring octal buffering with low-voltage compatibility between 2 V and 3.6 V. Ensure the application demands three-state output capability for shared bus lines. Verify that the required propagation delay and output drive current meet system timing and load specifications compared to higher voltage alternatives.

Part Context

This part belongs to the 74LVX244 family of octal buffers and line drivers. It shares functional similarities with other LVX series components but is distinct from HCT or LCX variants due to its specific voltage range and speed characteristics. The SOIC-20 package provides a standard footprint for surface-mount integration in compact electronic designs.
