LOW_POWER_SCHMITT

Published:2009/7/2 20:32:00 Author:May | From:SeekIC

Uses two NAND gates from SN74L00 NAND package and one NOR gate (used as inverter) from CD4001AE CMOS package to make low-power Schmitt trigger. NAND gates are connected to form RS flip-flop. Q goes high when input voltage is greater than 2.1 V, and other output does not go low until input voltage is less than 1.2 V.Both polarities of output signal are available.-R.
