The CD4051BE from Texas Instruments is a CMOS single 8-channel analog multiplexer\/demultiplexer with logic-level conversion. It can switch analog signals up to 20V peak-to-peak with digital control from 3V to 20V. Featuring low ON resistance (125\u03a9 typical at 15V), bidirectional signal paths, and break-before-make switching, it is packaged in a 16-pin PDIP for through-hole prototyping and production.<\/p>\n

It can switch analog signals up to 20V peak-to-peak using 3-bit binary address control, with low 125\u03a9 ON resistance and ultra-low \u00b110 pA OFF leakage. The break-before-make switching and bidirectional signal paths make it ideal for analog signal routing, sensor multiplexing, and data acquisition systems.","working_principle":"The CD4051BE uses CMOS transmission gates to connect one of eight analog channels (Y0-Y7) to a common output (COM) based on a 3-bit binary address (A, B, C). An active-high inhibit (INH) input disables all channels when asserted. The internal decoding logic selects the appropriate transmission gate pair (one PMOS, one NMOS in parallel) to form a low-resistance bidirectional switch. Break-before-make switching ensures no two channels are simultaneously connected. The VEE pin allows negative analog signal handling when dual supplies are used, enabling signal swing below ground.","pin_description":"\n
