Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when TTL-level control signals are required within a 5 V system. The DHVQFN14 package offers a compact footprint suitable for space-constrained designs. Ensure thermal management accounts for the 250 mW power dissipation limit of the SOT762-1 package under high ambient temperatures.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the 74HCT4066 family of quad analog switches manufactured by Nexperia. It utilizes HCT technology to bridge CMOS analog switching capabilities with TTL logic input requirements. The BQ suffix specifically denotes the DHVQFN14 leadless package variant designed for surface-mount assembly.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitutes include the 74HCT4066D-Q100,11 (SOIC-14 package) and the 74HCT4066BZ (DHXQFN14 package). Verify pinout compatibility and package dimensions before substitution.

Analog Switches, Multiplexers, Demultiplexers FAQ

Is the VCC pad on the DHVQFN14 package electrically connected?

No, the VCC pad on terminal 14 is not a supply pin. There is no electrical or mechanical requirement to solder it; if soldered, it should remain floating or connected to VCC.

What is the maximum input voltage for the 74HCT4066BQ?

The input voltage must not exceed the supply voltage (VCC), which ranges from 4.5 V to 5.5 V for the HCT version.

How does the ON resistance vary with supply voltage?

The ON resistance decreases as the supply voltage increases. At 4.5 V, the maximum is 142 Ohms, while typical values drop to 45 Ohms at 6.0 V and 35 Ohms at 9.0 V.
