SN74LVTH241DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH241DW is an octal buffer and line driver designed for low-voltage 3.3-V VCC operation with TTL interface capability to 5-V systems. It features two independent 4-bit drivers with separate output-enable inputs (1OE, 2OE). The device supports unregulated battery operation down to 2.7 V and includes active bus-hold circuitry on data inputs to eliminate external pullup/pulldown resistors. It provides Ioff and power-up 3-state support for hot insertion applications. The SOIC-20 package operates from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation with 5-V input and output voltages while operating at 3.3-V VCC
• Active bus-hold circuitry maintains unused or undriven inputs at a valid logic state without external components
• Provides Ioff and power-up 3-state functionality to prevent damaging current backflow during hot insertion
• ESD protection exceeds JESD 22 standards with 2000-V human-body model and 200-V machine model ratings

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused inputs?

The SN74LVTH241DW features active bus-hold circuitry on its data inputs. This 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 feature?

The Ioff circuitry disables the outputs when VCC is 0 V, preventing damaging current backflow through the device. This supports hot-insertion applications by ensuring safe power-down states.
