| Parameter | ||
|---|---|---|
| Supply voltage | - | Same 4000B envelope. |
| Memory & Peripherals | - | Its sibling 4052 switches differential pairs (X/Y together) for balanced lines. |
| Compatibility Level | - | Functional Equivalent |
| Component Category | Analog Multiplexers / Switches | - |
| Core & Architecture | - | Three independent SPDT switches with three separate control pins (not binary decoding) in the same 16-pin body - the member for signal routing and audio-path switching where three simple throws beat one multiplexer. |
| Firmware Notes | - | The row map to keep by the bench: 4051 one-of-eight, 4052 differential one-of-four, 4053 three SPDT. The body is shared, the schematic meaning is not - a 4053 in a 4051 socket passes three signals in ways nobody drew. |
| Hardware Notes | - | Shared 16-pin map with different internal assignments. |
| Lead Time Advantage | - | Shenzhen Spot Stock (24-48h Dispatch) |
| 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. | - |
