This bus is called the Inter-IC or I2C-bus. Only two bus lines are required: a serial data line (SDA) and a serial clock line (SCL). Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 kbit/s in the Standard-mode, up to 400 kbit/s in the Fast-mode, up to 1 Mbit/s in the Fast-mode Plus (Fm+), or up to 3.4 Mbit/s in the High-speed mode. 1442125286808710770774 PSP 751.0 KB None None documents None 1442125286808710770774 /docs/en/user-guide/UM10204.pdf 750958 /docs/en/user-guide/UM10204.pdf UM10204 documents N N 2016-07-12 I2C-bus specification and user manual /docs/en/user-guide/UM10204.pdf /docs/en/user-guide/UM10204.pdf User Guide N 132339537837198660 2024-10-24 pdf N en Oct 1, 2021 132339537837198660 User Guide Y N I2C-bus specification and user manual Fact Sheet Fact Sheet 1 3 1.0 English PCA9701/03 and PCA9702/04 Fact Sheet 1538084686791705121139 PSP 176.0 KB None None documents None 1538084686791705121139 /docs/en/fact-sheet/PCA970x.pdf 176041 /docs/en/fact-sheet/PCA970x.pdf PCA970x documents N N 2018-09-27 PCA9701/03 and PCA9702/04 Fact Sheet /docs/en/fact-sheet/PCA970x.pdf /docs/en/fact-sheet/PCA970x.pdf Fact Sheet N 736675474163315314 2023-06-22 pdf N en Sep 24, 2018 736675474163315314 Fact Sheet Y N PCA9701/03 and PCA9702/04 Fact Sheet Package Information Package Information 2 4 1.1 English 1455079215079728313090 PSP 215.4 KB None None documents None 1455079215079728313090 /docs/en/package-information/SOT994-1.pdf 215444 /docs/en/package-information/SOT994-1.pdf SOT994-1 documents N N 2019-09-26 plastic thermal enhanced very very thin quad flat package;
