Feature:1. This is a very convenient 16 channel CD74HC4067 analog/digital multiplexer/demultiplexer.2. 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.3. 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.4. The internal switch is bidirectional, with a low on resistance and off leakage, and to prevent cross talk, please turn off the switch first and then on.5. Drive it to a high level, and it will completely disconnect the common pins (all switches are disconnected).Specification:@font-face{font-family:"Times New Roman";}@font-face{font-family:"";}@font-face{font-family:"Calibri";}@font-face{font-family:"Arial";}p.MsoNormal{mso-style-name:;mso-style-parent:"";margin:0pt;margin-bottom:.0001pt;mso-pagination:none;text-align:justify;text-justify:inter-ideograph;font-family:Calibri;mso-fareast-font-family:;mso-bidi-font-family:'Times New Roman';font-size:10.5000pt;mso-font-kerning:1.0000pt;}span.msoIns{mso-style-name:"";text-decoration:underline;text-underline:single;color:blue;}span.msoDel{mso-style-name:"";text-decoration:line-through;color:red;}@page{mso-page-border-surround-header:no;mso-page-border-surround-footer:no;}@page Section0{}div.Section0{page:Section0;}Item Type: Analog Multiplexer16-channel analog signal switch with CD74HC4067Analog Signal Input: C0-C15 16 channelsAnalog Output: DIGChannel Control: S0-S3Package List:10 x Packs of CD74HC4067 Analog Multiplexer Note:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
