Best 2 to 1 Multiplexer

Treedix TCA9548A I2C Multiplexer Breakout Board 8 Channel Expansion Board with pi Header for Arduino

The TCA9548A Breakout board supports communicating with multiple I2C devices with the same address, making it easy to interface with them..
TCA9548A multiplexer features: bidirectional eight-channel I2C multiplexer, active low reset input.
The default address of this expander is 0x70, the address can be changed, and can be set within 0x70~0x77..
In the address of 0x70~0x77, 8 expanders can be cascaded, and each expander can be connected to 8 devices with the same address, so that the same I2C port can be connected to 64 devices with the same address and can be used normally..
The chip is compatible with 3V and 5V and can be used with any logic level.

8 Channel CCTV Video Multiplexer Color Quad Processor compatible with all Analog Security Cameras. NOT Compatible with 720P/1080P AHD / TVI / CVI / HD-SDI CCTV Cameras..
Multiple display modes: 8 camera view, 4 camera view, 2 camera view, single camera view, PIP (picture in picture).
NTSC and PAL Video Format Supported. Resolution PAL: 720 x 576.
8 Channel BNC Video Inputs, 1 BNC VCR In, 1 BNC VCR Out, 1 BNC Monitor. Image Freeze Function, Selectable Image Zoom Area, Video Loss Detection, Motion Detection, Auto sequence.
Power Supply adapter, remote control and user manual included..

Because the multiplexer can also process digital signals, you can use it to transfer TTL-level serial data to multiple devices through pipe or transfer from multiple devices..
This is a very convenient 16 channel CD74HC4067 analog/digital multiplexer/demultiplexer..
The internal switch is bidirectional, with a low on resistance and off leakage, and to prevent talk, please turn off the switch first and then on..
It is suitable for digital and analog signals (voltage cannot be higher than VCC) and can be connected in either direction. To control this, please connect the four digital outputs to the address selection pin of the chip (SO-S3) and send it the binary address of the desired channel..
Drive it to a high level, and it will completely disconnect the common pins (all switches are disconnected)..
