The switch status, either open or closed, is transferred to the microprocessor unit (MCU) through a serial peripheral interface (SPI). Individually selectable input currents are available in Normal and Low-power (LPM) modes, as needed for the application. 1417640273906725959333 PSP 1.1 MB None None documents None 1417640273906725959333 /docs/en/data-sheet/MC33978.pdf 1115227 /docs/en/data-sheet/MC33978.pdf MC33978 N N 2017-02-08 MC33978, 22 Channel Switch Detection Interface with Programmable Wetting Current Data Sheet /docs/en/data-sheet/MC33978.pdf /docs/en/data-sheet/MC33978.pdf Data Sheet N Y 980000996212993340 2024-08-22 pdf N en Aug 20, 2024 Data Sheet t520 データ・シート Data Sheet Y N MC33978, 22 Channel Switch Detection Interface with Programmable Wetting Current Data Sheet false ja ja アプリケーション・ノート Application Note 4 2 2.0 Chinese 1319753989104702481752zh PSP 7.6 MB Registration without Disclaimer None documents Extended 1319753989104702481752 /secured/assets/documents/zh/application-note/AN4388.pdf 7584935 /secured/assets/documents/zh/application-note/AN4388.pdf AN4388 documents Y N 2016-10-31 AN4388: Quad Flat Package (QFP) – Application Note /secured/assets/documents/zh/application-note/AN4388.pdf https://www.nxp.com.cn/webapp/Download?colCode=AN4388&docLang=zh Application Note N 645036621402383989 2024-01-19 zh May 10, 2022 645036621402383989 Application Note Y N AN4388,四方扁平封装(QFP) - 应用说明 3 English Providing guidelines for the handling and board mounting of NXP's QFP packages.
