CD74HC4067E

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4067E is a single 16:1 analog multiplexer/demultiplexer manufactured by Texas Instruments. It utilizes silicon gate CMOS technology to provide high-speed switching with low power consumption, comparable to LSTTL speeds. The device features a wide analog input voltage range and bidirectional signal flow capabilities. Key electrical parameters include a maximum on-resistance of 160 ohms, a maximum propagation delay of 300 ns, and an operating supply voltage range from 2 V to 6 V. It supports a broad temperature range from -55 °C to +125 °C and is housed in a 24-pin PDIP package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Bidirectional switching allows any analog input to function as an output and vice versa within the supply voltage range.
• High noise immunity ensures reliable operation with defined noise margins relative to the supply voltage.
• Integrated enable control disables all switches to the off state when the control signal is high.

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal gating and modulation circuits
• Data acquisition systems requiring channel selection
• Audio and video signal routing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the PDIP-24 through-hole package configuration. Confirm RoHS compliance status for the specific manufacturing lot. Ensure the ordering part number matches the required logic family (HC vs HCT) and pinout compatibility with the target PCB footprint.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring 16-channel analog switching with standard CMOS logic levels. The HC series operates between 2 V and 6 V, suitable for general-purpose digital and analog interfaces. Consider the HCT variant if direct LSTTL logic compatibility at 5 V is required. Evaluate the 160 ohm on-resistance against signal integrity requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the CD74HC4067 family of 16-channel analog multiplexers. It shares functional characteristics with other members like the CD74HC4067M96 but differs in packaging. The E suffix specifically denotes the plastic dual-in-line package, distinguishing it from surface-mount variants such as SSOP or SOIC packages.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other CD74HC4067 variants with different packages, such as CD74HC4067M96 (SOIC) or CD74HC4067SM96 (SSOP). Verify that the replacement maintains the same 24-pin count and pinout assignment to ensure mechanical and electrical compatibility.
