74HCT241D-Q100J

Overview

The Nexperia 74HCT241D-Q100J is an octal buffer and line driver featuring three-state outputs, designed for automotive applications. 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 provides non-inverting logic with two independent output enable inputs (1OE active LOW, 2OE active HIGH) controlling four outputs each. It includes input clamp diodes for interfacing voltages exceeding VCC and meets AEC-Q100 Grade 1 qualification standards.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards
• Non-inverting octal bus interface with dual independent three-state control
• High noise immunity and robust latch-up performance exceeding JESD 78 Class II Level B
• Integrated ESD protection meeting ANSI/ESDA/JEDEC JS-001 class 2 and JS-002 class C3 requirements

Applications

• Automotive electronic systems requiring qualified logic components
• Octal bus interface circuits in vehicle networks
• Line driving applications in mixed-voltage environments

Procurement Notes

Verify the specific package variant against project requirements, as the D suffix denotes the SO20 plastic small outline package (SOT163-1). Confirm that the ordering suffix matches the intended reel or cut tape configuration. Ensure design compliance with the specified operating temperature range and supply voltage limits before finalizing procurement orders.

Selection Notes

Select this component when an octal buffer with three-state capability is required for automotive designs. The HCT series ensures TTL-compatible input levels while maintaining CMOS low power dissipation. Verify that the SO20 package dimensions fit the PCB layout constraints and that the thermal derating characteristics align with the application's power dissipation needs.

Part Context

This part belongs to the 74HCT241-Q100 family of octal buffers and line drivers. It shares functional similarities with other 74HCT series devices but is specifically optimized for automotive reliability. The Q100 designation indicates adherence to strict automotive quality standards, distinguishing it from standard commercial logic families.

Replacement Considerations

The 74HCT241PW-Q100 serves as a pin-compatible alternative utilizing the TSSOP20 package instead of the SO20 format.
