SN74LV244APW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244APW is an octal buffer and line driver from Texas Instruments, belonging to the LV logic series. It features eight non-inverting channels with three-state outputs housed in a 20-pin TSSOP package. The device operates within a supply voltage range of 2 V to 5.5 V and supports a wide operating temperature range from -40°C to +85°C. Key electrical characteristics include a maximum propagation delay of 6.5 ns at 5 V and output drive capabilities of 16 mA for both high and low states. It includes independent output enable inputs for each group of four drivers.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the ordering part number matches the required pin configuration and electrical specifications for your design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust signal integrity across a wide voltage range. The LV series offers improved performance over older logic families while maintaining compatibility. Consider the TSSOP package constraints regarding thermal dissipation and board space. Verify that the 16 mA drive current meets the load requirements of the connected circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of the broader SN74LV244 family of octal buffers. It shares functional similarities with other Texas Instruments logic drivers but is distinguished by its specific low-voltage CMOS technology and packaging options. The 'A' designation typically indicates an advanced version within the series, often featuring optimized electrical parameters compared to earlier iterations.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LV244ADWR is a documented substitute offering identical functionality in a tape-and-reel format. SN74LV244ADW provides the same electrical performance in a SOIC-20 package. Verify pinout compatibility and package dimensions before substituting these alternatives.
