Frequently Asked Questions
What is the configuration and on-resistance of the CD74HC4051M?
The CD74HC4051M is an 8:1 analog multiplexer with a single common port and eight individually selectable channel inputs. The typical on-resistance is 160 ohm across the 2V to 6V supply range, which is low enough for most audio and low-frequency signal routing but should be accounted for in precision voltage-divider or impedance-sensitive designs.
What is the bandwidth and channel isolation of the CD74HC4051M?
The CD74HC4051M offers a nominal bandwidth of 200 MHz, allowing it to switch high-frequency analog signals including RF and video with acceptable insertion loss. Off-state isolation is 73dB nominal, meaning inactive channels attenuate the switched signal by over 70dB, minimizing crosstalk and interference between simultaneously present signals on unselected inputs.
How are channels selected on the CD74HC4051M?
The CD74HC4051M uses three binary address inputs (A, B, C) to select one of eight analog channels (Y0 through Y7) to connect to the common Z terminal. A low active enable (INH) input disables all channels when asserted high. The address decoding follows a standard 3-bit binary code, making it directly compatible with microcontroller GPIO pins for software-controlled signal routing.
What package does the CD74HC4051M use?
The CD74HC4051M is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package with JESD-30 code R-PDSO-G16. The SOIC package measures approximately 9.9mm x 3.9mm with 1.27mm pin pitch, balancing compact PCB footprint with ease of hand soldering and inspection, making it popular in prototyping and production environments alike.
What is the supply voltage range of the CD74HC4051M and what logic families is it compatible with?
The CD74HC4051M operates from a 2V to 6V supply, covering both 3.3V and 5V logic systems. The HC (High-speed CMOS) logic family control inputs are compatible with standard LVCMOS and LVTTL logic levels at both 3.3V and 5V, allowing seamless interfacing with modern microcontrollers, FPGAs, and legacy TTL systems without level-shifting in most applications.
