SAA1305T On/off Logic IC

The SAA1305T is an on/off Logic IC, intended for use in car Radios to Interface between a Microcontroller and various input signals such as ignition, low supply detection, on/off key and external control signals. The SAA1305T CAN replace an existing on/off Logic built-up with Discrete components. The SAA1305T contains 8 inputs with accurate Schmitt triggers and clamp circuits. The main function of this IC is an intelligent I/O expander with 2 modes of operation: 1. Normal I/O expander: the Microcontroller (master) is running and the SAA1305T acts like a slave. 2. Sleep mode of the total application: the Microcontroller is stopped and the SAA1305T acts like a master. During an event, the Microcontroller is awakened. The Communication with the IC is performed via the I2C-bus (400 kHz). Extra functions of the SAA1305T are: LED blinker circuit One-day watch Watchdog Timer
