74HCT541PW-Q100J

Overview

The Nexperia 74HCT541PW-Q100J is an octal non-inverting buffer and line driver featuring three-state outputs, housed in a TSSOP20 package. It operates within a supply voltage range of 4.5 V to 5.5 V. The device includes two active-low output enable inputs (OE1 and OE2) that force outputs into a high-impedance state when asserted HIGH. Input clamp diodes allow interfacing with voltages exceeding VCC using current-limiting resistors. It meets AEC-Q100 Grade 1 qualification for automotive use.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Dual active-low output enables for flexible bus management
• Input clamp diodes facilitate safe interfacing above supply voltage
• High noise immunity with robust latch-up protection

Applications

• Automotive electronic systems requiring qualified logic components
• Bus-oriented memory and register interfaces
• Clock drivers and buffering applications
• Data acquisition systems

Procurement Notes

Verify the specific ordering suffix matches the required tape and reel configuration. Confirm the package variant corresponds to the SOT360-1 designation. Ensure the component grade aligns with project requirements for automotive reliability standards before finalizing procurement orders.

Selection Notes

Select this component when TTL-level input compatibility is required alongside CMOS performance characteristics. The HCT series ensures direct interface with standard TTL logic families. Verify that the operating temperature range covers the intended environmental conditions for the target application design.

Part Context

This part belongs to the Nexperia 74HCT541-Q100 family of octal buffers. It shares functional similarities with other 74-series logic devices but is specifically optimized for automotive environments. The PW suffix indicates the thin shrink small outline plastic package type used for surface-mount assembly.

Replacement Considerations

Direct replacements include the 74HC541PW-Q100J for CMOS input levels or the 74AHCT541PW-Q100J for advanced high-speed CMOS operation. Verify pinout compatibility and electrical specifications against the original design requirements before substitution.
