(*1) AO is the reverse phase of AO, when output is active. (the same phase, when output is inactive): CF5732EA, GA
(*2) AO is complete reverse phase of AO. (even output is inactive.): CF5732FA, HA, JA, KA
(*3) When AI is held at 1/2 V
DD
, the alarm reference, frequency is output at AO and AO.
Input Debouncing Circuit
Setting bouncing delay time prevents the circuit from the
erroneous operation by AI input bouncing (chattering.)
