74HC4067PW,118

Overview

The Nexperia 74HC4067PW,118 is a single-pole 16-throw analog switch (SP16T) housed in a TSSOP24 package. It operates with a supply voltage range of 2.0 V to 10.0 V and features four digital select inputs (S0-S3), sixteen independent I/Os (Yn), one common I/O (Z), and an active-low enable input (E). The device exhibits low ON resistance, typically 80 Ω at 4.5 V, 70 Ω at 6.0 V, and 60 Ω at 9.0 V. Dynamic performance includes propagation delays up to 22 ns at 4.5 V and turn-on/turn-off times reaching 83 ns. It offers high noise immunity, CMOS low power dissipation, and ESD protection exceeding 2000 V (HBM).

Feature Summary

• Single-pole 16-throw analog switching architecture for multiplexing applications.
• Wide operating supply voltage range supporting 2.0 V to 10.0 V operation.
• Built-in 'break before make' functionality to prevent signal shorting during channel transitions.
• High noise immunity and robust latch-up performance compliant with JESD 78 standards.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and tape/reel specifications. Ensure the component meets required environmental standards such as RoHS compliance. Cross-reference the manufacturer part number with distributor catalogs to validate authenticity and availability status prior to procurement.

Selection Notes

Select this component when a 16-channel analog switch is required within a 2.0 V to 10.0 V supply range. The TSSOP24 package is suitable for surface-mount designs requiring space efficiency. Consider the typical ON resistance values relative to the specific supply voltage to ensure signal integrity. Verify that the CMOS logic levels for address inputs match the system's control voltage requirements.

Part Context

This component belongs to the 74HC/HCT series of logic switches manufactured by Nexperia. It serves as a standard solution for routing multiple analog or digital signals through a single path. The PW suffix indicates the TSSOP24 plastic thin shrink small outline package variant, distinguishing it from SO or QFN package options within the same functional family.

Replacement Considerations

Direct replacements include other 74HC4067 variants in different packages, such as 74HC4067D (SO24) or 74HC4067BQ (DHVQFN24). Automotive qualified versions like 74HC4067PW-Q100 are available if AEC-Q100 certification is required. Ensure pinout compatibility and electrical parameter alignment when substituting.

FAQ

What is the function of the Enable (E) input?

The Enable input is active LOW. When E is HIGH, all switches are turned off, isolating the common terminal Z from the independent terminals Yn.

How does the device handle input voltages exceeding VCC?

The inputs include clamp diodes, allowing the use of current-limiting resistors to interface with voltages in excess of VCC without damaging the device.

What is the typical ON resistance at a 4.5 V supply?

At a supply voltage (VCC) of 4.5 V, the typical ON resistance is 80 Ω.
