... Any device connected bus can transmit and receive signals; however, only the master connected to the host side of the MAX7356/ MAX7357/MAX7358 should address the device. The MAX7356/MAX7357/MAX7358 are available in 24-pin TSSOP and TQFN packages and are specified over the extended -40° ...

... For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability ...

... The MAX7356/MAX7357/MAX7358 family of devices has selectable device addresses through three external inputs. The slave address consists of 4 fixed bits (A6–A3 set to 1110); followed by 3 pin-programmable bits (A2, A1, A0), as shown in Figure 7. The addresses ...

... If the fault still exists, the fault handling sequence repeats and the faulty bus will not be allowed to connect to the host bus. The RST on the MAX7356 can be used to reset the MAX7356 by a host. The RST input is an active-low sig- nal. By asserting this signal low for a minimum of t externally, the MAX7356 resets its I and deselects all channels ...

... SCL output. Each transmission consists of a START condition sent by a master, followed by the MAX7356/MAX7357/ MAX7358’s 7-bit slave address plus R/W bit, and then optionally 1 or more data bytes, and finally a STOP con- dition (Figure 10) ...

... A write to the MAX7356 starts with the master transmitting the slave address with the R/W bit set low. The MAX7356 acknowledges the slave address. The master can then issue a STOP condition after the acknowledge (Figure 14), but typically the master proceeds to transmit one or more bytes of data ...

The MAX7356 acknowledges the slave address. The master can read 1 byte from the switch control register and then issue a STOP condition (Figure 17) ...

... DATA BYTE FROM THE SWITCH CONTROL REGISTER in Basic Mode The pass gates of the MAX7356/MAX7357/MAX7358 are designed so V levels transferred from one bus to another. The power- supply voltage of the part should be selected larger than one VGS bus voltage in the system. This ensures that the analog switches do not allow current to flow from higher volt- age buses to lower voltage buses ...
