74LVC541APW-Q100J

Overview

The Nexperia 74LVC541APW-Q100J is an octal buffer and line driver featuring 3-state outputs, housed in a TSSOP20 (SOT360-1) package. It operates within a supply voltage range of 1.2 V to 3.6 V, with inputs tolerant up to 5.5 V. The device includes two active LOW output enable inputs (OE1, OE2) and supports partial power-down via IOFF circuitry. It is qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C.

Feature Summary

• Features Schmitt-trigger inputs for tolerance of slow rise and fall times
• Includes IOFF circuitry to prevent damaging backflow current during partial power-down
• Provides direct interface compatibility with TTL logic levels
• Supports mixed 3.3 V and 5 V environments through 5 V tolerant I/O

Applications

• Automotive electronic systems requiring AEC-Q100 Grade 1 qualification
• Mixed voltage bus driving between 3.3 V and 5 V domains
• Partial power-down applications utilizing IOFF functionality

Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP20 package variant required for your design constraints. Confirm that the AEC-Q100 Grade 1 qualification aligns with your automotive application temperature and stress requirements. Ensure input signals remain within the specified 5.5 V tolerance limits to maintain device integrity.

Selection Notes

Select this component when an octal buffer with 3-state control is needed for automotive or industrial environments. It is suitable for designs requiring direct interfacing with TTL levels and operation across a wide supply voltage range. Consider the TSSOP20 package dimensions and thermal characteristics for PCB layout planning.

Part Context

This part belongs to the Nexperia 74LVC541A-Q100 family of octal buffers. The 'P' in the model number indicates the TSSOP20 plastic thin shrink small outline package. The 'Q100' designation confirms its qualification under the Automotive Electronics Council standard, distinguishing it from non-automotive variants.

Replacement Considerations

The 74LVC541AD-Q100 serves as a functional substitute using the SO20 (SOT163-1) package. Designers must account for differences in physical footprint and thermal dissipation characteristics when transitioning between the TSSOP20 and SO20 packages.
