The TLV3604 has a single functional mode and is operational when the power supply voltage is greater than
the minimum operating voltage. On the other hand, the TLV3605 and TLV3607 have an active and shutdown mode. The TLV3605 and TLV3607 are in shutdown mode when the SHDN pin is logic low. To allow for easy interface with 1.8V FPGAs and CPUs, the SHDN pin is 1.8 V logic compliant and independent of the comparator power supply.
