74HCT7541D-Q100J

Overview

The Nexperia 74HCT7541D-Q100J is an octal Schmitt trigger buffer and line driver with three-state outputs, housed in a SO20 (SOT163-1) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL-level inputs and non-inverting outputs. Key electrical parameters include a propagation delay of up to 48 ns at 4.5 V, input capacitance of 3.5 pF, and power dissipation capacitance of 32 pF. It meets AEC-Q100 Grade 1 qualification standards.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards for reliable operation in vehicle environments.
• Schmitt-trigger inputs provide high noise immunity and transform slowly changing signals into sharply defined output transitions.
• Dual active-low output enable inputs allow flexible control over the three-state OFF-state condition.

Applications

• Automotive data bus buffering and signal conditioning
• Line driving for noisy industrial communication interfaces
• Octal data storage and transfer between logic families

Procurement Notes

Verify the specific suffix 'J' against the manufacturer's current ordering information to confirm packaging details and compliance status. Ensure the design accounts for the SO20 package thermal derating characteristics above 109 °C. Confirm that the TTL input levels align with the source system voltage requirements before finalizing procurement specifications.

Selection Notes

Select this component when automotive reliability and high noise immunity are required for octal data lines. The HCT variant ensures compatibility with TTL logic levels, distinguishing it from HC versions that use CMOS levels. Consider the dual OE pins for complex bus arbitration scenarios requiring independent output control segments.

Part Context

This part belongs to the Nexperia 74HCT7541-Q100 family of octal buffers. It shares functional similarities with other 74-series drivers but is distinct due to its Schmitt-trigger inputs and automotive qualification. The D-package variant specifically utilizes the SO20 plastic small outline form factor.

Replacement Considerations

The 74HC7541D-Q100J serves as a logical alternative if CMOS input levels are acceptable instead of TTL. Verify pinout compatibility and ensure the replacement maintains the required AEC-Q100 Grade 1 qualification for the target application.
