SN74LVTH241DBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH241DBR 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 utilizes active bus-hold circuitry on data inputs to maintain valid logic states without external resistors. The component is housed in a 20-pin SSOP package and is designed for hot-insertion applications via Ioff and power-up 3-state support.

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 eliminate the need for external pullup or pulldown resistors
• Provides Ioff and power-up 3-state functionality to prevent damaging current backflow and driver conflicts during hot insertion

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed-mode 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 'DBR' corresponds to the SSOP-20 package and tape-and-reel carrier format. Confirm that the RoHS compliance status and lead finish match project requirements. Ensure the operating temperature range of -40°C to +85°C aligns with the environmental specifications of the target application. Cross-reference the manufacturer part number against the latest TI documentation to confirm current production status.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer is required for 3.3-V logic families interfacing with 5-V systems. The LVTH series is appropriate for applications needing high drive capability with low static power consumption. Consider the SSOP-20 package constraints regarding board space and thermal dissipation. Verify that the separate output-enable inputs meet the control architecture requirements for bidirectional bus management.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVTH241 family of octal buffers and line drivers. It is part of Texas Instruments' Low-Voltage TTL (LVTH) logic portfolio, designed specifically for low-voltage operations. The family shares functional similarities with other octal drivers but is optimized for 3.3-V supply voltages while maintaining compatibility with legacy 5-V logic levels through its mixed-mode design capabilities.
