74LVC541ADB,118

Overview

The Nexperia 74LVC541ADB,118 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V and supports overvoltage tolerant inputs and outputs up to 5.5 V. The device includes IOFF circuitry for partial power-down mode operation, preventing damaging backflow currents. It provides Schmitt-trigger action at all inputs to tolerate slower rise and fall times. The component is specified for ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Features two active LOW output enable inputs (OE1 and OE2) that control the high-impedance OFF-state of the associated outputs.
• Includes IOFF circuitry that disables outputs when powered down to prevent potentially damaging backflow current through the device.
• Provides direct interface capability with TTL levels while accepting inputs driven from either 3.3 V or 5 V devices.

Applications

• Translator applications in mixed 3.3 V and 5 V environments
• Partial power-down mode operations utilizing IOFF circuitry
• Octal bus buffering and line driving functions

Procurement Notes

Verify the specific ordering suffix 'ADB' against official Nexperia documentation to confirm package type and temperature range specifications. Confirm compliance with RoHS and REACH regulations as stated in the product data sheet. Ensure design compatibility with the specified operating conditions and absolute maximum ratings before procurement.

Selection Notes

Select this component for designs requiring an 8-bit buffer with 5 V tolerance on both inputs and outputs. Consider the wide supply voltage range suitable for low-power CMOS applications. Evaluate the need for dual output enables and partial power-down capabilities. Verify thermal performance requirements against the specified total power dissipation limits for the target application environment.
