DCL54xx01A
6. Functional Description (1) DCL540C01A/ DCL540D01A
INPUT OUTPUT VDD1 VDD2 COMMENTS (Vix) (VOx) L L Normal Operation PU H H PU OPEN Default mode Default DCL540C01A=L , DCL540D01A=H PD L or OPEN PU X PD Undetermined When VDD2 is unpowered, a channel output is undetermined. PD L or OPEN Don’t use, since a certain voltage will be output through the PD X H - internal ESD circuit. PU= Powered up (VDD≥2.25 V), PD= Powered down (VDD≤1.7 V), H= High level, L= Low level, X= Don’t care
