The TLV3601-Q1 has a single functional mode and is active when the power supply voltage is greater than 2.4V. The TLV3603-Q1 has two modes of operation. The first is an active mode where the output reflects the condition at the inputs when an external resistor is connected to ground on the LE/HYS pin. The second is a latch mode where the output is held at its last active state when the LE/HYS pin is pulled low. The TLV3603-Q1 returns to active mode after a short delay when the pin is pulled high.
