74HC7541PW-Q100J

Overview

The Nexperia 74HC7541PW-Q100J is an octal Schmitt trigger buffer and line driver featuring three-state outputs, housed in a TSSOP20 package (SOT360-1). 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 meets AEC-Q100 Grade 1 qualification standards for automotive applications.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards
• Schmitt-trigger inputs provide noise immunity and jitter-free signal transformation
• Dual active-low output enables control high-impedance OFF-states
• CMOS construction ensures low power dissipation and high noise immunity

Applications

• Automotive electronic systems requiring qualified logic components
• Bus-oriented transmissions utilizing 3-state buffering
• Clock distribution circuits demanding Schmitt-trigger noise filtering
• Driving capacitive loads across wide voltage ranges

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and temperature rating. Ensure that the procurement channel provides valid traceability records consistent with automotive quality requirements. Confirm compliance with current RoHS and REACH directives before finalizing orders.

Selection Notes

Select this component when designing systems requiring eight-channel buffering with defined hysteresis for noisy environments. The dual enable pins offer flexible control over data flow directionality. Verify that the system voltage falls within the specified 2.0 V to 6.0 V range and that thermal management accounts for the TSSOP20 package derating characteristics.

Part Context

This part belongs to the Nexperia 74HC7541-Q100 family of octal buffers. It shares functional similarities with other 74-series drivers but is distinguished by its automotive qualification and Schmitt-trigger input architecture. The PW suffix specifically denotes the TSSOP20 plastic thin shrink small outline package variant.

Replacement Considerations

The 74HCT7541PW-Q100J serves as a compatible alternative within the same family, offering TTL-compatible input levels instead of CMOS levels while maintaining identical pinout and packaging.
