74ALVC541PW,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ALVC541PW,118 is an octal non-inverting buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 1.65 V to 3.6 V and complies with JEDEC standards JESD8-7, JESD8-5, and JESD8C/JESD36. The device incorporates Schmitt trigger inputs for tolerance to slow rise and fall times, alongside IOFF circuitry that prevents damaging backflow current during partial power-down conditions. It provides latch-up protection exceeding 250 mA per JESD78 Class II.A and includes ESD protection rated at over 2000 V (HBM) and 1000 V (CDM).

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features two active LOW output enable inputs (OE0 and OE1) to control the high-impedance OFF-state.
• Includes IOFF circuitry to disable outputs and prevent backflow current when powered down.
• Schmitt trigger action on all inputs ensures tolerance to slow signal transition rates.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down applications requiring backflow current prevention.
• Bus-oriented systems utilizing three-state logic.
• Mixed-signal environments interfacing TTL levels with CMOS devices.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '118' against official Nexperia documentation to confirm the TSSOP20 package configuration and reel specifications. Ensure compatibility with system requirements regarding operating temperature ranges and electrical characteristics before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring an octal buffer with independent output enables and robust protection against partial power-down scenarios. Consider the TSSOP20 package dimensions and thermal derating characteristics if operating near maximum ambient temperatures or power dissipation limits.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ALVC family of octal buffers and line drivers manufactured by Nexperia. It shares functional similarities with other variants in the series but is distinguished by its specific TSSOP20 packaging and detailed electrical compliance with established JEDEC standards for low-voltage CMOS logic.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the 74ALVC541D and 74ALVC541BQ from Nexperia, which offer identical functionality in SO20 and DHVQFN20 packages respectively. Cross-manufacturer equivalents should be evaluated based on pinout compatibility and matching electrical specifications.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the IOFF circuitry function?

The IOFF circuitry disables the outputs to prevent potentially damaging backflow current through the device when it is in a powered-down state.

What controls the three-state outputs?

The outputs are controlled by two input pins, OE0 and OE1. A HIGH level on either OEn causes the associated outputs to assume a high-impedance OFF-state.
