The MAX7318 supports hot insertion. All port pins, the INT output, SDA, SCL, and the slave address inputs AD02 remain high impedance in power-down (V+ = 0V) with up to 6V asserted upon them. The MAX7318 is available in 24-pin SO, SSOP, TSSOP, and thin QFN packages and is specified over the -40C to +125C automotive temperature range. For applications requiring an SMBus timeout function, refer to the MAX7311 data sheet.
