Description:
The phrase "Dell Hef4067b" appears to be a misnomer
. Dell, a computer manufacturer, does not produce the HEF4067B integrated circuit. The HEF4067B is a generic, 16-channel analog multiplexer/demultiplexer made by semiconductor companies like Nexperia (which took over the semiconductor business of Philips) and NXP Semiconductors. Online electronics retailers sometimes include manufacturer prefixes like "Dell" in their product titles, which may be a source of the confusion.
About the HEF4067B analog multiplexer/demultiplexer:
- Function: The HEF4067B is a 16-channel analog multiplexer/demultiplexer, also known as a Single-Pole 16-Throw (SP16T) analog switch.
- Purpose: It allows a user to connect one common input/output pin (Z) to any of the 16 independent input/output pins (Y0-Y15).
- Bidirectional switches: The analog switches within the chip are bidirectional, meaning they can be used to either multiplex (select one of 16 inputs to a single output) or demultiplex (route a single input to one of 16 outputs).
-
Control mechanism: A 4-bit digital address (
A0cap A sub 0
𝐴0
to
A3cap A sub 3𝐴3
) and an active-LOW enable input (
Ēcap E bar𝐸̄
) are used to control which of the 16 switches is active.
- When the enable input is LOW, the address selects one of the 16 channels.
- When the enable input is HIGH, all channels are turned off, placing them in a high-impedance state.
- Power requirements: The chip has a wide supply voltage range, typically operating from 3.0 V to 15.0 V.
-
Common applications:
- Routing analog or digital signals.
- Signal gating.
- Expanding the number of inputs for a single analog-to-digital converter on a microcontroller
