This IC internally routes a common signal pin (SIG) to one of 16 channel pins, working with both analogue and digital signals in either direction. Control which channel is active using 4 digital address lines (S0–S3) — connect up to 16 sensors using only 5 microcontroller pins.\n\nThe bidirectional switches support voltages between ground and VCC with low on-resistance and break-before-make switching to prevent crosstalk. An enable pin allows you to completely disconnect all channels when driven high.\n\nKey Features\n\n\n16 Channels – Multiplex/demultiplex analogue or digital signals\n\nBidirectional – Signals can flow in either direction\n\nOperating Voltage – 2 V to 6 V\n\nOn Resistance – 70 Ω at 4.5 V\n\nBreak-Before-Make – 6 ns switching at 4.5 V\n\nEnable Pin – Disconnect all channels when not in use\n\nOperating Temperature – −55 °C to +125 °C\n\n4-Bit Address – S0–S3 select the active channel\n\n\nIdeal For\n\nExpanding analogue inputs on microcontrollers\nRouting serial data to/from multiple devices\nSensor arrays and multi-channel data acquisition\nI²C, SPI, or UART signal routing (with multiple boards)\n\n\nPackage Contents\n\n1× SparkFun CD74HC4067 MUX Breakout\n\n\nResources\n\nCD74HC4067 Datasheet (PDF)\nSchematic (PDF)\nDesign Files (GitHub)\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":10136,"title":"Default Title","sku":"SF-BOB-09056","price":12.85,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":443,"option1":"Default Title"}]}
