SN74LVTH244ADB

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH244ADB is an octal buffer and line driver from Texas Instruments, utilizing the LVTH logic series. It features eight non-inverting channels organized into two groups of four, each with independent three-state output control via separate Output Enable (OE) pins. The device operates within a supply voltage range of 2.7V to 3.6V and is housed in a 20-pin SSOP package. It provides high drive capability with low-level output currents up to 64mA and high-level currents up to -32mA. Designed for robust performance, it supports mixed-mode signal operations across inputs and outputs, ensuring compatibility with various digital systems while maintaining signal integrity.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant, as the SN74LVTH244A family includes both SSOP and SOIC options. Confirm that the required operating temperature range aligns with commercial specifications. Ensure design compatibility with the 2.7V to 3.6V supply voltage constraints. Check for any specific ordering suffixes that may indicate tape-and-reel packaging versus tubes if applicable to the specific sub-part number.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-speed buffering with strong drive capabilities in low-voltage environments. It is suitable for applications needing isolation between driving sources and loads. Consider the SSOP package dimensions for PCB layout constraints. Evaluate the need for three-state outputs to manage shared bus architectures effectively without signal contention.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH244A series, which represents advanced low-voltage technology optimized for high-speed operation. It serves as a bridge between older 5V-compatible designs and modern low-voltage logic families. The LVTH series is characterized by its ability to interface with 5V inputs while operating at lower supply voltages, making it versatile for legacy system upgrades.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVTH244ADBR is a direct functional substitute offering identical electrical characteristics but packaged in SOIC-20 instead of SSOP-20. Designers must verify pinout compatibility and physical footprint differences before swapping these variants.
