DS90CP02SP

Texas Instruments · Signal Switches, Multiplexers, Decoders · WQFN-28-EP(5x5)

DS90CP02SP from Texas Instruments, in a WQFN-28-EP(5x5). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference to LVDS and CMOS circuitry.
2 GND power_in Ground reference to LVDS and CMOS circuitry.
3 GND power_in Ground reference to LVDS and CMOS circuitry.
4 GND power_in Ground reference to LVDS and CMOS circuitry.
5 SEL1 input LVTTL select control input that, with SEL0, sets which input each output is connected to.
