- In detail
- BrandFreescale Semiconductor
The 33972 Multiple Switch Detection Interface with suppressedwake-Up is designed to detect the closing and opening of up to 22switch contacts. The switch status, either open or closed, is transferredto the microprocessor unit (MCU) through a serial peripheral interface(SPI). The device also features a 22-to-1 analog multiplexer for readinginputs as analog. The analog input signal is buffered and provided onthe AMUX output pin for the MCU to read. Package :32SOIC W Operating Temperature: -40 to 125 °C Category: Interface Misc Manufacturer: Freescale Semiconductor
