SN74LVTH541NS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH541NS 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 inputs and outputs on opposite package sides to facilitate PCB layout. The device supports unregulated battery operation down to 2.7 V and includes 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 3-state control gate utilizes two active-low inputs, placing all outputs in a high-impedance state if either input is high.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's Package Option Addendum to confirm the exact physical package type, such as SOIC (DW), SSOP (DB), or TSSOP (PW). Ensure the selected variant matches the required operating temperature range of -40°C to 85°C for commercial grade devices. Confirm RoHS compliance status and lead finish specifications via the official TI documentation before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits that require octal buffering between 3.3-V and 5-V logic domains. The SN74LVTH541NS is suitable for applications needing high drive strength and protection against ground bounce. Consider the package options available, including tube and tape-and-reel configurations, based on assembly requirements. Ensure that unused control inputs are tied to VCC or GND to guarantee proper device operation.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused inputs?

The SN74LVTH541NS incorporates active bus-hold circuitry on its data inputs. This feature holds undriven inputs at a valid logic state, eliminating the need for external pullup or pulldown resistors.

What is the function of the dual output enable inputs?

The 3-state control gate consists of two active-low inputs (OE1 and OE2) functioning as a 2-input AND gate. If either OE1 or OE2 is high, all outputs enter a high-impedance state.
