SN74LV244ANSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244ANSR is an octal buffer and line driver manufactured by Texas Instruments, belonging to the LV logic series. It features eight non-inverting channels with three-state outputs housed in a 20-SOIC package. The device operates within a supply voltage range of 2 V to 5.5 V. Key electrical parameters include a maximum propagation delay of 6.5 ns at 5 V, output currents of 16 mA for both high and low states, and a static current of 8 uA. It supports an operating temperature range from -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode operation allowing all ports to function with different voltage levels simultaneously
• Includes IOFF feature enabling partial power-down mode to prevent excessive current draw during insertion
• Provides enhanced electrostatic discharge protection exceeding JESD 22 standards for human model and charged device model

• Bus-oriented receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ANSR' corresponds to the SOIC-20 package and tape-and-reel packaging configuration. Confirm RoHS compliance status and ensure the component matches the SN74LV244A series specifications regarding voltage ranges and pinout assignments before integration into designs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring wide voltage compatibility between 2 V and 5.5 V. It is suitable for applications needing high-density bus driving with independent output enable controls. Consider its thermal performance and ESD robustness for industrial environments where signal integrity and reliability are critical.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV244A family of octal buffers. It shares functional similarities with other variants like SN74LV244ADW but differs in packaging and reel specifications. The LV series is designed to improve performance and density compared to older logic families while maintaining compatibility with standard digital interfaces.
