| Market Reality | The 405x row is the analog switch drawer of instrumentation and industrial design: the CD4051B selects one of eight channels with three address pins, the 4052 switches differential pairs four ways, the 4053 is three independent SPDT switches - all in the same 16-pin body with on-chip binary decoding, 20V-capable analog rails and hundred-ohm on-resistance of the 4000B generation. The naming deserves the wall chart it gets: across the row the last digit changes the channel topology, not the size or the pin count, and the 74HC405x twins - identical pinouts, faster and more linear - quietly cap the analog rails at 12V where the 4000B parts ran to 20. | The 405x row is the analog switch drawer of instrumentation and industrial design: the CD4051B selects one of eight channels with three address pins, the 4052 switches differential pairs four ways, the 4053 is three independent SPDT switches - all in the same 16-pin body with on-chip binary decoding, 20V-capable analog rails and hundred-ohm on-resistance of the 4000B generation.
