SN74LVC541APWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC541APWR is an octal buffer and line driver manufactured by Texas Instruments, featuring non-inverting logic with three-state outputs. It operates within a supply voltage range of 1.65V to 3.6V and supports mixed-mode operation, allowing inputs to tolerate voltages up to 5.5V while the device runs at lower levels. The component provides high drive capability with output currents of 24mA for both high and low states. It is housed in a 20-TSSOP surface-mount package and functions reliably across an industrial temperature range from -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode voltage environments by accommodating 5.5V tolerant inputs on devices powered by lower voltages
• Enables partial power-down mode functionality through Ioff circuitry to prevent backflow current during shutdown
• Provides high-drive performance with symmetrical 24mA output sourcing and sinking capabilities

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented communications systems requiring signal buffering
• Clock distribution circuits for driving multiple loads
• Memory and data register interfaces in mixed-voltage designs

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration intended for automated assembly processes. Ensure that the procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability. Confirm compliance with RoHS3 standards and check for any recent product change notices regarding marking or material composition updates before finalizing orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require interfacing between 3.3V logic domains and 5V peripherals without external level shifters. The wide operating voltage range allows flexibility in power supply design. Consider the 20-TSSOP package dimensions for PCB layout constraints. Verify that the required drive current does not exceed the specified limits under worst-case thermal conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC541A family of octal buffers and line drivers. It shares functional similarities with other variants such as the SN74LVC541ADWR, which utilizes a SOIC-20 package instead of TSSOP. The LVC series is characterized by its low voltage CMOS technology, offering reduced power consumption compared to older logic families while maintaining high-speed performance suitable for modern digital applications.
