SN74LVTH244ADWE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH244ADWE4 is an octal buffer and line driver from the LVTH logic series, manufactured by Texas Instruments. It features eight non-inverting inputs and outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 2.7 V to 3.6 V. Key electrical parameters include a high-level output current of -32 mA and a low-level output current of 64 mA. Propagation delay is specified at 2.3 ns at 3.3 V. It supports three-state outputs and functions across a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides octal buffering with three-state output control for bus-oriented applications.
• Supports mixed-mode operation allowing simultaneous use of 3.3-V and 5-V I/O lines.
• Designed for partial power-down mode compatibility to minimize standby currents.

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

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the 'DW' suffix corresponds to the SOIC-20 package variant. Ensure the component meets the required industrial temperature range specifications for your application environment before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 3.3-V logic levels with high drive capability. It is suitable for replacing older ABT or LVT devices where lower voltage operation is needed. Consider the SOIC-20 package constraints for PCB layout. Verify that the 2.7 V minimum supply voltage aligns with the system's power rail stability.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH244A family of octal buffers. It is distinct from the SN74LV244 (LVT) which supports wider voltage ranges, and the SN74ABT244 (ABT) which operates at 5 V. The LVTH series specifically targets 3.3-V applications with improved performance over standard LVT devices in terms of speed and drive strength.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVTH244ADW is the non-compliant predecessor. SN74LVTH244APWR offers the same functionality in a TSSOP package.
