74HC240BQ-Q100,115

Overview

The Nexperia 74HC240BQ-Q100,115 is an octal buffer and line driver featuring inverting 3-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 utilizes a DHVQFN20 package (SOT764-1) with side-wettable flanks for automated optical inspection. It includes two output enable inputs (1OE and 2OE), where a HIGH level forces the outputs into a high-impedance OFF-state.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1 standard
• CMOS low power dissipation combined with high noise immunity
• Latch-up performance exceeding 100 mA per JESD 78 Class II Level B
• DHVQFN package with side-wettable flanks enabling automated optical inspection

Applications

• Automotive applications requiring automotive-grade logic components
• Bus-oriented transmissions utilizing 3-state buffering
• Clock drivers and buffer circuits for digital systems

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the AEC-Q100 Grade 1 qualification requirements for your target application environment. Ensure compatibility with the specified temperature range and supply voltage limits during system design validation.

Selection Notes

Select this component when an octal inverting buffer with 3-state control is required in a compact surface-mount form factor. The DHVQFN20 package offers thermal enhancement and facilitates automated assembly inspection. Consider the wide supply voltage range and robust latch-up protection for reliable operation in electrically noisy environments.

Part Context

This part belongs to the Nexperia 74HC240-Q100 family of octal buffers and line drivers. It is pin-compatible with Low-Power Schottky TTL (LSTTL) standards. The device functions as a dual octal inverting buffer with independent output enables, providing flexible configuration options for bus-driven architectures.

Replacement Considerations

The 74HCT240BQ-Q100 serves as a compatible alternative within the same package, offering TTL-level input compatibility instead of CMOS levels.
