SN74LVTH244ADW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH244ADW is an octal buffer and line driver from Texas Instruments, utilizing the LVTH logic series. It features eight non-inverting channels with three-state outputs housed in a 20-pin SOIC package. The device operates on a supply voltage range of 2.7 V to 3.6 V, supporting standard 3.3 V digital systems. It exhibits a propagation delay of 2.3 ns at 3.3 V, with high-level output current of -32 mA and low-level output current of 64 mA. The component supports an operating temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DW' corresponds to the tube packaging format rather than tape-and-reel configurations. Confirm that the RoHS compliance status matches current regulatory requirements for your target market. Ensure the component grade aligns with the specified commercial/industrial temperature range of -40°C to +85°C for your application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed performance is required within a strict 3.3 V power budget. The LVTH technology offers faster switching speeds compared to standard LVC families while maintaining low power consumption. Consider the SOIC-20 package dimensions for PCB layout constraints and ensure adequate thermal management for the specified current drive capabilities.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH244A family of octal buffers. It shares functional similarities with the SN74LVC244ADW but utilizes ABT-like technology for improved speed. The 'DW' suffix indicates a plastic small-outline package with a 7.5 mm width. It serves as a direct replacement for legacy 74FCT244 devices in modern low-voltage designs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVTH244ADWE4 is a verified equivalent variant with identical electrical specifications and functionality. Both parts utilize the same LVTH logic series and pinout configuration, ensuring drop-in compatibility for design updates or supply chain diversification without circuit modification.
