74HC240D-Q100,118

Overview

The Nexperia 74HC240D-Q100,118 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and complies with JEDEC standards JESD8C and JESD7A. The device includes two output enables, each controlling four outputs, allowing configuration as two 4-bit buffers or one 8-bit buffer. It supports operation from -40 °C to +85 °C and up to +125 °C. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.

Feature Summary

• Octal bus interface with non-inverting three-state outputs
• Dual output enable control for flexible bus management
• Automotive qualification in accordance with AEC-Q100
• High noise immunity and low power CMOS dissipation

Applications

• Automotive electronic systems requiring robust logic buffering
• Bus-oriented memory and data transmission applications
• Clock drivers and buffer circuits in mixed-voltage environments

Procurement Notes

Verify the specific suffix and package variant against the official Nexperia datasheet to ensure compatibility with your design requirements. Confirm that the AEC-Q100 automotive grade certification meets your project's reliability standards. Check for any recent Product Change Notifications (PCNs) regarding manufacturing site changes or marking updates before finalizing procurement orders.

Selection Notes

Select this component when an octal buffer with three-state capability is required for automotive or industrial applications. Ensure the operating voltage aligns with the 2.0 V to 6.0 V range. Consider the thermal performance and ESD protection levels if the environment demands high robustness. Verify pinout compatibility if replacing existing designs.

Part Context

This part belongs to the Nexperia 74HC series of high-cmOS logic devices, specifically designed for automotive applications under the Q100 qualification standard. It complements other octal drivers like the 74HC241 and provides a reliable solution for bus interfacing where high impedance states are necessary for multi-driver configurations.

Replacement Considerations

Direct substitutes include the 74HC241D-Q100,118, which offers similar functionality but with inverted output enable logic. Other compatible parts in the 74HC family may require verification of pinout and electrical characteristics to ensure seamless integration.
