selector15

Selector15 is a 15-channel analog multiplexer designed to route one of fifteen input signals to a single output, or to route a single input to one of fifteen outputs, under digital control. It is used in data acquisition, instrumentation, and signal routing where compact, switchable signal paths are required. The device supports both single-ended and differential configurations and operates from standard supply rails typically in the 3.3 to 5.0-volt range. It provides low on-resistance, fast turn-on/turn-off times, and high isolation when channels are deselected, reducing crosstalk in mixed-signal systems. A flexible control interface supports parallel binary select lines as well as serial control such as SPI-like protocols, enabling integration with microcontrollers and FPGA logic.

Protection and packaging: Input clamps and ESD protection are common features, along with overcurrent protection on each channel. Selector15 is offered in compact surface-mount packages and in through-hole variants to fit a range of board designs. The device is commonly used in laboratory instrumentation, portable measurement gear, audio and signal routing consoles, and sensor arrays where multiple signals must be selectively monitored or combined.

Variants and evolution: The family includes Selector15-L for low-noise analog signals, Selector15-C for compact layouts, and Selector15-D differential-input versions for balanced signals. Some revisions add enhanced leakage resistance and extended temperature ranges for industrial environments.

History and context: Introduced in the early 2020s as part of a broader trend toward high-channel-count multiplexers, Selector15 competes with other 15:1 mux products and has been adopted in education kits and prototyping platforms. It is documented in product catalogs and application notes that describe typical use cases and PCB layout guidelines.
