74HC541D-Q100J

Overview

The Nexperia 74HC541D-Q100J is an octal non-inverting buffer and line driver with three-state outputs, qualified to AEC-Q100 Grade 1 for automotive use. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features two active-low output enables (OE1, OE2) and input clamp diodes for overvoltage interfacing. Packaged in a 20-lead SO20 plastic small outline package (SOT163-1), it complies with JEDEC standards JESD8C and JESD7A.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Dual active-low output enable inputs for flexible bus management
• High noise immunity with latch-up performance exceeding 100 mA per JESD 78 Class II Level B
• Input clamp diodes allow current limiting resistors for voltages exceeding VCC

Applications

• Automotive engine control units
• Body control modules
• Transmission control units
• Electronic instrument clusters

Procurement Notes

Verify the specific suffix 'J' against official Nexperia documentation to confirm tape-and-reel packaging configuration. Confirm that the D-package designation corresponds to the SOT163-1 (SO20) footprint. Ensure the procurement channel provides valid traceability records required for AEC-Q100 automotive components.

Selection Notes

Select this component when designing systems requiring eight buffered channels with high-impedance isolation capabilities. The wide supply voltage range accommodates mixed-voltage environments. Verify that the CMOS input levels align with the driving source logic family, distinguishing it from the HCT variant which utilizes TTL levels.

Part Context

This part belongs to the Nexperia 74HC541-Q100 series of octal buffers. It shares functional architecture with the TSSOP20 PW variant but utilizes the SO20 D-package. The series is designed for robust signal transmission in electrically noisy automotive environments while maintaining low power dissipation characteristics typical of CMOS technology.

Replacement Considerations

The 74HCT541D-Q100 serves as a direct logical alternative if TTL input levels are required instead of CMOS levels. Other variants within the same family include the 74HC541PW-Q100, which offers identical functionality in a TSSOP20 package.
