74LVC541ADB,112

Overview

The Nexperia 74LVC541ADB,112 is an octal buffer and line driver featuring five-volt tolerant inputs and outputs with three-state capability. It operates within a supply voltage range of 1.2 V to 3.6 V and includes Schmitt-trigger action for noise immunity. The device incorporates IOFF circuitry to prevent backflow current during partial power-down states. It utilizes the SO20 plastic small outline package (SOT163-1) and supports ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Features two active-low output enable inputs (OE1 and OE2) for independent control of bus direction and state.
• Provides overvoltage tolerance on all inputs and outputs up to 5.5 V, enabling direct interfacing with 5 V logic systems.
• Includes dedicated IOFF circuitry that disables outputs to eliminate potentially damaging backflow currents when the device is powered down.

Applications

• Translating data signals between mixed 3.3 V and 5 V logic environments
• Driving high-capacitance or long-distance transmission lines as a line driver
• Managing bidirectional data buses in memory and storage interface architectures

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the package type and temperature grade. Confirm compliance with relevant environmental directives such as RoHS and REACH requirements before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring eight-channel buffering with simultaneous 5 V tolerance and low-voltage operation. Ensure the application demands three-state isolation capabilities and robust input protection against voltage spikes exceeding the primary supply rail.

Part Context

This part belongs to the 74LVC family of logic integrated circuits manufactured by Nexperia. The LVC series is characterized by its wide operating voltage range and compatibility with both 1.8 V and 3.3 V standards while maintaining performance suitable for general-purpose digital logic applications.

Replacement Considerations

The 74LVC541APW serves as a functional alternative utilizing the TSSOP20 package. Verify pinout compatibility and thermal dissipation characteristics when substituting packages within the same logical family.
