Yes, Schmitt trigger designed for this, they don't draw excessive "crossove= r" current. Does add hysteresis, hopefully that's acceptable. Can get them = in various 1 and 2 input configurations, not sure if i've seen a 3 input on= e. -------- Original message --------From: Jason White Date: 8/30/19 9:01 AM (GMT+12:00) To: "Microcontroller discu= ssion list - Public." Subject: [EE] Logic gate draw exces= sive current in undefined region, smallest replacement? Hello PIC List!I ha= ve a design that uses the 74LVC1G332. I found that it draws about 45mAwhen = 2.2V is applied to all three inputs and does not even get hot. Thepurpose o= f this gate is to square a very slow moving voltage, the thresholdvoltage a= ccuracy and stability is unimportant. Hysteresis is not required.My applica= tion is space and power constrained. Is there a logic gate thatdoes not exh= ibit this behavior? (100uA in the undefined would be much moreacceptable th= an 45mA) Maybe a schmitt trigger would be designed toaccommodate this?Other= wise I think I will be forced to use a comparator which would add two(or th= ree) resistors to the design for a reference voltage. A singletransistor so= lution would p! robably not be optimal due to the limited gain.Thanks!Jason White-- http:/= /www.piclist.com/techref/piclist PIC/SX FAQ & list archiveView/change your = membership options athttp://mailman.mit.edu/mailman/listinfo/piclist --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
