74HC4066D-Q100,118

Overview

The Nexperia 74HC4066D-Q100,118 is a quad single-pole single-throw analog switch qualified to AEC-Q100 Grade 1 standards for automotive use. It operates within a supply voltage range of 2.0 V to 10.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device features four independent switches with active HIGH enable inputs. Maximum on-resistance reaches 128 Ω at 2.0 V and 95 Ω at 9.0 V. Propagation delay is typically 8 ns at 2.0 V and 2 ns at 9.0 V. Turn-on time is up to 150 ns at 2.0 V, while turn-off time is up to 225 ns at 2.0 V.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1) for reliable operation in vehicle environments.
• Wide operating temperature range extending from -40 °C to +125 °C for harsh condition compatibility.
• Input clamp diodes allow interface to voltages exceeding VCC when used with current limiting resistors.

Applications

• Automotive signal routing and switching circuits
• Battery management system signal paths
• Industrial control signal multiplexing

Selection Notes

Select this component for designs requiring CMOS-level logic control and wide voltage tolerance. Ensure load currents remain within the 25 mA absolute maximum rating. Verify that required on-resistance values align with specific supply voltages, as RON varies significantly between 2.0 V and 9.0 V rails.

Part Context

This part belongs to the 74HC4066-Q100 family of quad analog switches. It shares functional characteristics with the 74HCT4066-Q100 but utilizes CMOS input levels rather than TTL-compatible thresholds. The D suffix indicates the SO14 plastic small outline package variant.

Replacement Considerations

The 74HC4066BQ-Q100 offers identical electrical performance in a DHVQFN14 package. The 74HC4066PW-Q100 provides the same function in a TSSOP14 package. Direct pin-to-pin replacement requires matching the physical footprint and thermal dissipation requirements of the target PCB layout.

FAQ

How does the ON resistance vary with supply voltage?

The ON resistance decreases as the supply voltage increases. At 2.0 V, it can reach 128 Ω, whereas at 9.0 V, it drops to approximately 95 Ω under similar load conditions.

What is the purpose of the input clamp diodes?

The input clamp diodes enable the use of current limiting resistors to safely interface inputs to voltages that exceed the VCC supply rail without damaging the internal circuitry.

Is this device suitable for high-frequency signal transmission?

Yes, the device exhibits a -3 dB frequency response of approximately 180 MHz at 4.5 V and 200 MHz at 9.0 V, supporting high-speed analog signal routing.
