APPLICATION NOTE
(1) Input circuit
Input terminals of (2), (3), (12) and (13) Pin are all high active type and have a hysteresis. 3 µA Typ. of input current is required. The input c ircuit is an ac tive hig h t ype, as shown in t he diag ram. Wh en voltage higher t han t he spec ified VIN (H) is applied, the output is logic “H”. When voltage lower than the specified VIN (L) is applied or if the input is grounded, the output is logic “L”. Si nce the input current IN flows to the inpu...
