SN74LV244ADWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244ADWR is an octal buffer and line driver manufactured by Texas Instruments, belonging to the 74LV logic series. It features two independent four-bit buffers with three-state outputs, designed for high-speed memory address driving and bus-oriented applications. The device operates within a wide supply voltage range of 2V to 5.5V and supports mixed-mode voltage operations across all ports. It utilizes CMOS technology and is housed in a 20-pin SOIC package. Key electrical characteristics include a maximum propagation delay of 6.5ns at 5V, typical output ground bounce (VOLP) less than 0.8V, and typical output overshoot (VOHV) greater than 2.3V under standard conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode voltage operation allowing inputs to operate from 0V to 5.5V while VCC ranges from 2V to 5.5V
• Includes Ioff circuitry to prevent excessive current draw during partial power-down mode
• Provides enhanced signal integrity through optimized output impedance and reduced ground bounce

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers for high-density systems
• Clock drivers requiring precise timing control
• Bus-oriented receivers and transmitters in telecommunications infrastructure

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DWR' corresponds to the tape-and-reel packaging format when sourcing components. Confirm that the device meets RoHS and REACH compliance requirements as indicated by manufacturer documentation. Ensure compatibility with existing PCB footprints for the 20-SOIC package before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring wide voltage flexibility and high-speed buffering capabilities. The LV series offers superior performance compared to legacy LS or ALS families. Consider the three-state output feature for efficient bus sharing in complex digital architectures where multiple devices connect to common data lines.
