I'm trying to use 4 ADG1414 Analog Switches for a DUT mux (from a bus). I have them connected in the following manner:
RESET/VL is tied to the 5V supply.
The DUT_CS is controlled by a 3x8 decoder.
During debug/testing of this circuit the first bank AS6 (DUT 1-8) work correctly, as soon as I try and shift a 1 through to connect DUT9 (AS6), the -15V supply loads down (current limited), the 5V supply draws an additional ~150mA and the switch for DUT9 does not close. When I cycle the power supplies, the board remains in this condition where the -15V supply is loaded down and the 5V supply drawing the additional 150mA.
Has this behavior been observed by anyone else? Is there some usage error I have? Trying to understand the condition that would cause this failure/issue.
