... MAX6317/MAX6318/MAX6320/MAX6321 are also capa- ble of asserting a reset should the µP become stuck in an infinite loop. The MAX6316L/MAX6318LH/MAX6319LH feature an active-low reset output, while the MAX6317H/ MAX6318_H/MAX6319_H/MAX6321HP/MAX6322HP feature an active-high reset output. RESET is guaran- teed logic low and RESET is guaranteed logic high for V down to 1V ...
