SN74LVTH241PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH241PWR is an octal buffer and line driver from the LVTH logic series, manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and features non-inverting data transmission with separate output-enable inputs (1OE, 2OE). The device supports mixed-mode signal operation, allowing 5-V input and output voltages during 3.3-V VCC operation. It includes active bus-hold circuitry on data inputs to eliminate external pullup/pulldown resistors. Packaged in a 20-pin TSSOP, it provides 3-state outputs for hot-insertion support via Ioff and power-up 3-state circuitry.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation with 5-V tolerant inputs and outputs while operating at 3.3-V VCC
• Features active bus-hold circuitry on data inputs to maintain valid logic states without external resistors
• Provides Ioff and power-up 3-state functionality to prevent damaging current backflow and driver conflicts during insertion or power transitions

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed-signal buffering between 5-V systems and 3.3-V environments
• Hot-insertion applications requiring controlled power-up and power-down states
• Octal bus drivers for unregulated battery operation down to 2.7 V

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the tape-and-reel packaging format in the TSSOP-20 package. Confirm that the RoHS compliance status and lead finish (NIPDAU) match the project requirements. Ensure the operating temperature range of -40°C to 85°C aligns with the environmental specifications of the target application.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal, non-inverting buffer with 3-state outputs is required for 3.3-V logic systems interfacing with 5-V signals. The LVTH series is suitable for applications needing low power consumption and high noise immunity. Consider the TSSOP-20 package constraints regarding board space and thermal dissipation compared to other available packages like SOIC or SSOP.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH241 family of octal buffers and drivers. It is functionally similar to other LVTH devices but distinguished by its non-inverting polarity and specific pinout configuration. The 'PWR' suffix indicates a specific manufacturing variant optimized for surface-mount assembly in reel packaging, differing from tube-packed versions like the PW suffix.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused inputs?

The SN74LVTH241PWR utilizes active bus-hold circuitry on its data inputs. This feature holds unused or undriven inputs at a valid logic state, eliminating the need for external pullup or pulldown resistors.

What is the purpose of the Ioff circuitry?

The Ioff circuitry ensures that the outputs are disabled when the device is powered down. This prevents damaging current from flowing back through the device into the power supply or connected circuits.
