74LVC541APW,112

Overview

The Nexperia 74LVC541APW,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 inputs up to 5.5 V. The device includes two active LOW output enable inputs (OE1 and OE2) and utilizes Schmitt-trigger action for noise immunity. It incorporates IOFF circuitry to prevent backflow current during partial power-down conditions. The component is housed in a TSSOP20 package (SOT360-1) and is rated for ambient temperatures from -40 °C to +125 °C.

Feature Summary

• Provides five-volt tolerant inputs and outputs for mixed voltage environments
• Includes dedicated IOFF circuitry to disable outputs and prevent damaging backflow currents when powered down
• Features Schmitt-trigger inputs to ensure tolerance against slow input rise and fall times

Applications

• Translating signals between 3.3 V and 5 V logic systems
• Driving high-capacitance or transmission-line loads
• Managing clock buffers and bus-oriented communications

Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP20 plastic thin shrink small outline package with SOT360-1 designation. Confirm that the required temperature range covers -40 °C to +125 °C for your application environment. Ensure design compatibility with the 1.2 V to 3.6 V supply voltage limits before finalizing procurement specifications.

Selection Notes

Select this component when an eight-bit non-inverting buffer with three-state control is required. It is suitable for designs needing direct interfacing with TTL levels and overvoltage tolerant inputs. Consider the TSSOP20 package dimensions if space constraints favor thin shrink outlines over standard SO packages.

Part Context

This part belongs to the 74LVC541A family of octal buffers manufactured by Nexperia USA Inc. The family offers variants in different packages, including SO20 and DHVQFN20. The APW variant specifically denotes the TSSOP20 configuration, providing a compact solution for surface-mount applications requiring robust signal buffering capabilities.

Replacement Considerations

Cross-reference with other 74LVC541A variants such as the 74LVC541AD,118 for SO20 packaging or the 74LVC541ABQ,115 for DHVQFN20 packaging if pinout compatibility allows.
