74HC4351D-Q100J

Overview

The Nexperia 74HC4351D-Q100J is an automotive-grade, single-pole octal-throw analog switch (SP8T) designed for 8:1 multiplexer and demultiplexer applications. It features three digital select inputs (S0 to S2), eight independent I/Os (Yn), a common I/O (Z), and two enable inputs (E1, E2). The device includes address latches controlled by LE and operates within a wide supply voltage range of 2.0 V to 10.0 V. It supports dual supplies with VEE ranging from -5 V to +5 V relative to GND. Qualified to AEC-Q100 Grade 1, it functions reliably from -40 °C to +125 °C in a 20-lead SO plastic small outline package.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Integrated address latching capability via the LE input pin
• Wide analog signal handling with input voltage range from -5 V to +5 V
• Built-in logic level translation enabling 5 V logic control of ±5 V analog signals

Applications

• Analog multiplexing and demultiplexing systems
• Digital multiplexing and demultiplexing circuits
• Signal gating applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure the component meets the required AEC-Q100 Grade 1 specifications for your target application environment. Cross-reference the datasheet revision date to guarantee access to the latest electrical characteristics and mechanical dimensions before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring robust analog switching with integrated address latching. The HC variant offers a wide supply voltage range suitable for diverse logic levels. Verify that the required ON resistance and leakage currents align with the specific operating conditions defined in the static characteristics tables. Consider the thermal dissipation limits if multiple switches are active simultaneously at high temperatures.

Part Context

This part belongs to the Nexperia 74HC4351-Q100 family of 8-channel analog multiplexers. It shares functional similarities with other SP8T devices but is distinguished by its specific automotive qualification and latch integration. The 'D' designation indicates the SO20 package, while the '-Q100' suffix confirms its compliance with automotive reliability standards, differentiating it from standard commercial logic counterparts.

Replacement Considerations

Direct replacements include the 74HCT4351D-Q100J for TTL-compatible logic levels. Other compatible parts within the same family may offer identical pinouts and functionality. Verify that any substitute maintains the same AEC-Q100 Grade 1 qualification and package dimensions to ensure seamless integration into existing automotive designs without board modifications.
