SN74LV244ADWE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244ADWE4 is an octal buffer and line driver from the Texas Instruments LVTH logic series, housed in a 20-pin SOIC package. It operates within a supply voltage range of 2.7 V to 3.6 V and supports non-inverting signal transmission across eight channels with three-state outputs. The device features a propagation delay of 2.3 ns at 3.3 V, high-level output current of -32 mA, and low-level output current of 64 mA. It functions reliably between -40°C and +85°C with a quiescent current of 5 uA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides octal buffering and driving capabilities for high-density bus applications
• Supports mixed-mode operation allowing inputs and outputs to operate at different voltages
• Includes partial power-down mode capability to minimize standby current consumption

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the E4 suffix indicates lead-free construction and RoHS compliance when sourcing. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C meets your environmental specifications. Cross-reference the datasheet for specific electrical characteristics under your intended load conditions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for systems requiring 3.3V ABT performance with mixed-voltage interface support. It serves as a suitable replacement for standard LV244 variants where lower voltage operation is required. Consider the SOIC-20 package for surface-mount assembly constraints. Evaluate the 2.3 ns propagation delay against your system timing budgets.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH244A family of octal buffers and drivers. It shares functional similarities with other LVTH devices but is distinguished by its specific voltage range and package configuration. The E4 suffix denotes environmental compliance features consistent with Texas Instruments' manufacturing standards for this product line.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVTH244ADW is the non-E4 variant of the same logical function and package.
