74HC7541D-Q100J

Overview

The Nexperia 74HC7541D-Q100J is an octal Schmitt trigger buffer and line driver featuring three-state outputs. 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 includes two active LOW output enable inputs (OE1, OE2) and input clamp diodes for interfacing with voltages exceeding VCC. It complies with AEC-Q100 Grade 1 standards for automotive applications.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standard
• Schmitt trigger inputs transform slowly changing signals into sharply defined jitter-free outputs
• High noise immunity with unlimited input rise and fall times
• ESD protection exceeds 2000 V (HBM) and 1000 V (CDM)

Applications

• Automotive electronic systems requiring robust signal buffering
• Interfaces handling voltages exceeding the logic supply rail
• Applications demanding high noise immunity and jitter-free output

Procurement Notes

Verify the specific suffix 'D' corresponds to the SO20 package type when ordering. Confirm that the 'Q100' designation aligns with required automotive grade specifications. Ensure the 'J' suffix matches the intended tape and reel packaging configuration. Cross-reference the full part number against the manufacturer's current datasheet revision to confirm availability and compliance status.

Selection Notes

Select this component for designs requiring eight buffered channels with Schmitt trigger action. The HC variant provides CMOS input levels suitable for standard logic families. Consider the wide operating temperature range and extended supply voltage capabilities for harsh environments. Verify that the SO20 package dimensions fit the available PCB footprint constraints.

Part Context

This component belongs to the Nexperia 74HC7541-Q100 family of octal buffers. It shares functional similarities with other 74-series logic devices but is specifically optimized for automotive reliability. The D-package variant utilizes a plastic small outline form factor, distinguishing it from TSSOP alternatives within the same logical series.

Replacement Considerations

The 74HCT7541D-Q100J serves as a compatible alternative within the same family, offering TTL-compatible input levels instead of CMOS levels.
