The MAX7311 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 MAX7311 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 I/Os without pullup resistors, refer to the MAX7312 data sheet.
