ELM742x makes it easy to design power circuits and contributes to extend battery life on account of the single power source, low voltage supply operating range (VDD㻢+1.0V) and also low power consumption. ELM742x introduces depletion transistors into the differential input stage, and has a wide input voltage range (VSS+0.1V 䌾 VDD㪄0.2V), and can drive the TTL and CMOS Logic IC on account of the N-ch opendrain output. 䂓 FEATURES 䊶Low voltage operation 䊶Low power consumption 䊶Wide operation voltage range : VDD 㻢 +1.0V : IDD (TYP.) = 0.6㱘A (VDD = 1.5V) : 1.0V 㻡 VDD 㻡 7.0V 䊶Wide input voltage range 䊶Output stage is N-ch opendrain type 䊶Very small SOT-25 package : VSS 䋫 0.1V 䌾 VDD㪄0.2V 䂓 APPLICATION 䊶 Battery㪄operated devices 䊶Micropower signal processing 䊶Low voltage analog circuits 䂓 PIN CONFIGURATION Pin No. 1 2 3 4 5 㪫㪦㪧㩷㪭㪠㪜㪮 㪌 㪋 㪄 㪈 㪂 㪉 㪊 Pin Name IN䋭 VDD IN䋫 OUT VSS 䂓 MARKING 㪪㪦㪫㪄㪉㪌 No. 㽲 㽳 㽴 㽲 㽳 㽴 Mark A 0䌾9 0䌾9 Contents ELM742x Lot No. Lot No. 䂓 SELECTION GUIDE Symbol 㩷㩷㪘㩷㪑 㪪㫅㪆㪧㪹㩷㫇㪸㪺㫂㪸㪾㪼 './Z 㫏 㪧㫉㫆㪻㫌㪺㫋㩷㪭㪼㫉㫊㫀㫆㫅 㩷㩷㪙㩷㪑 㪧㪹㩷㪄㩷㪝㫉㪼㪼㩷㫇㪸㪺㫂㪸㪾㪼 81 LOW VOLTAGE, LOW POWER CMOS VOLTAGE COMPARATOR ELM742x 䂓 MAXIMUM ABSOLUTE RATINGS 㩿㩷㪭㪪㪪㪔㪇㪭㩷㪀 Units Parameter Symbol Limits 㪪㫌㫇㫇㫃㫐㩷㪭㫆㫃㫋㪸㪾㪼 㪠㫅㫇㫌㫋㩷㪭㫆㫃㫋㪸㪾㪼 㪦㫌㫋㫇㫌㫋㩷㪭㫆㫃㫋㪸㪾㪼 㪦㫌㫋㫇㫌㫋㩷㪚㫌㫉㫉㪼㫅㫋 㪧㫆㫎㪼㫉㩷㪛㫀㫊㫊㫀㫇㪸㫋㫀㫆㫅 㪦㫇㪼㫉㪸㫋㫀㫅㪾㩷㪫㪼㫄㫇㪅㩷㪩㪸㫅㪾㪼 㪪㫋㫆㫉㪸㪾㪼㩷㪫㪼㫄㫇㪅㩷㪩㪸㫅㪾㪼 㪭㪛㪛 㪭㪠㪥 㪭㪦㪬㪫 㪠㪦㪬㪫 㪧㪻 㪫㫆㫇 㪫㫊㫋㪾 㪈㪇 㪭㪪㪪㪄㪇㪅㪊䌾㪭㪛㪛㪂㪇㪅㪊 㪈㪇 㪊㪇 㪊㪇㪇 㪄㪉㪇䌾㪂㪎㪇 㪄㪋㪇䌾㪂㪈㪉㪌 㪭 㪭 㪭 㫄㪘 㫄㪮 㷄 㷄 䂓 ELECTRICAL CHARACTERISTICS Parameter Symbol 㩷㪧㫆㫎㪼㫉㩷㪪㫌㫇㫇㫃㫐㩷㪭㫆㫃㫋㪸㪾㪼 㩷㪚㫆㫄㫄㫆㫅㩷㪤㫆㪻㪼㩷 㩷㪠㫅㫇㫌㫋㩷㪭㫆㫃㫋㪸㪾㪼 㪭㪛㪛 㪭㪠㪚 㩿㩷㪭㪪㪪㪔㪇㪭㪃㩷㪫㫆㫇㪔㪉㪌㷄㪃㩷㫌㫅㫃㪼㫊㫊㩷㫆㫋㪿㪼㫉㫎㫀㫊㪼㩷㫅㫆㫋㪼㪻㩷㪀 Min.
