74HCT4067DB,112

Analog Switches, Multiplexers, Demultiplexers Overview

The Nexperia 74HCT4067DB,112 is a single-pole 16-throw analog switch (SP16T) designed for analog or digital multiplexer/demultiplexer applications. It features four digital select inputs (S0-S3), sixteen independent inputs/outputs (Yn), a common input/output (Z), and an active LOW enable input (E). The device operates with TTL-level inputs and supports a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a maximum ON resistance of 180 Ohms at 4.5 V, propagation delay of 9 ns, turn-on time of 65 ns, and turn-off time of 60 ns. It functions within an ambient temperature range of -40 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific ordering suffix matches the required package type and thermal characteristics. Ensure compliance with RoHS directives and check for any end-of-life notices or obsolescence warnings associated with this specific part number before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a 16-channel analog switch with TTL input compatibility is required. Verify that the operating supply voltage remains within the 4.5 V to 5.5 V range to ensure proper logic level recognition. Consider the SSOP-24 package dimensions for PCB layout constraints and confirm that the thermal dissipation requirements are met within the specified operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the 74HCT series of CMOS logic devices manufactured by Nexperia. It is functionally equivalent to other industry-standard 16-channel analog switches but is specifically characterized for TTL input thresholds. The 'DB' suffix indicates the SSOP-24 plastic small outline package variant, distinguishing it from TSSOP or QFN versions within the same logical family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers include 74HC4067DB,112 and 74HCT4067PW,118. Verify pinout compatibility and electrical specifications such as ON resistance and propagation delay before substitution. Note that the 74HC4067 variant requires CMOS input levels rather than TTL.
