74HCT4066PW,118

Analog Switches, Multiplexers, Demultiplexers Overview

The Nexperia 74HCT4066PW,118 is a quad single-pole single-throw analog switch in a TSSOP14 package. It operates on a single supply voltage of 4.5 V to 5.5 V with an operating temperature range of -40 °C to +125 °C. The device features TTL-level inputs and provides four independent bidirectional switches. Key electrical parameters include a maximum ON resistance of 128 Ω at 4.5 V, a propagation delay of 36 ns, and a turn-off time of 53 ns. Input leakage current is limited to ±1.0 μA, while the maximum supply current is 40 μA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Ensure that the requested component matches the required temperature grade and compliance standards before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when TTL-compatible control signals are required for analog switching applications. Verify that the maximum ON resistance and leakage current specifications meet the circuit requirements within the 4.5 V to 5.5 V supply voltage range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the 74HCT4066 series, which is designed as a high-speed CMOS quad bilateral switch. It serves as a functional equivalent to other industry-standard quad analog switches but is distinguished by its specific HCT logic input thresholds and Nexperia's manufacturing specifications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The 74HCT4066D,118 (SOIC-14) offers identical electrical characteristics and functionality. Designers may consider this alternative if a wider body width package is preferred for thermal or mechanical reasons, provided pin-to-pin compatibility is maintained.
