74LVC541AD,112

Overview

The Nexperia 74LVC541AD,112 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 up to 5.5 V. The device includes IOFF circuitry for partial power-down applications. It utilizes Schmitt-trigger inputs to tolerate slow rise and fall times. The component is housed in a 20-lead SO plastic small outline package (SOT163-1) and functions across an ambient temperature range 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.
• Includes IOFF circuitry to disable outputs and prevent damaging backflow current during partial power-down.
• Provides direct interface capability with TTL levels and compatibility with mixed 3.3 V and 5 V environments.

Applications

• Translating signals between mixed 3.3 V and 5 V logic environments
• Providing bus-oriented connections requiring three-state control
• Driving capacitive or resistive loads on data buses

Procurement Notes

Verify the ordering suffix '112' corresponds to the specific tape-and-reel packaging configuration required for automated assembly processes. Confirm the package type matches the SOT163-1 designation for the SO20 footprint. Ensure the procurement documentation references the correct revision level to guarantee compliance with the latest JEDEC standards and electrical specifications.

Selection Notes

Select this component when designing systems requiring eight-bit buffering with independent output control. The wide supply voltage range allows operation in low-power applications down to 1.2 V. The 5.5 V input tolerance facilitates interfacing with legacy 5 V devices without additional level shifting components. Verify that the thermal dissipation requirements align with the specified derating curves for the SO20 package.

Part Context

This part belongs to the 74LVC family of CMOS logic devices, designed for low-voltage operation. The 74LVC541A variant specifically provides octal buffering capabilities. The AD suffix indicates the SO20 plastic small outline package version. This series is engineered for high noise immunity and low static power consumption, making it suitable for portable and battery-operated electronic equipment.

Replacement Considerations

The 74LVC541AD,118 is a verified substitute offering identical electrical characteristics and functionality. Both parts utilize the same SOT163-1 package and maintain pin-to-pin compatibility. Designers should verify that the alternative supplier's manufacturing process meets the same quality and reliability standards as the original Nexperia specification.
