... A5, A4, A3) are fixed to 1001[B]. The states of A2, A1 and A0 in the serial bit stream must match the states of the A2, A1 and A0 address inputs for the TCN75 to set- respond with an Acknowledge (indicating the TCN75 is HYST on the bus and ready to accept data). The Slave Address is represented in Table 3-1 ...

... Comparator/Interrupt Modes INT/CMPTR behaves differently depending on whether the TCN75 is in Comparator mode or Interrupt mode. Comparator mode is designed for simple thermostatic operation. INT/CMPTR will go active anytime TEMP exceeds T . When in Comparator mode, INT/ SET CMPTR will remain active until TEMP falls below T , whereupon it will reset to its inactive state. The ...

... Serial Port Operation The Serial Clock input (SCL) and bidirectional data port (SDA) form a 2-wire bidirectional serial port for pro- gramming and interrogating the TCN75. The following table indicates TCN75 conventions that are used in this bus scheme. DS21490C-page 8 TABLE 4-1: Term Transmitter The device sending data to the bus ...

... Acknowledge (ACK) provides a positive handshake between the host and the TCN75. The host releases SDA after transmitting eight bits then generates a ninth clock cycle to allow the TCN75 to pull the SDA line LOW to acknowledge that it successfully received the previous eight bits of data or address. ...
