19. IF Count Buffer

Although this explanation is for the LA1137N, it is identical for the LA1136N, except that the pin numbers are different.

Circuit operations

Pin 13 serves as both the count buffer input pin and output pin. When the control voltage with no load is HIGH 5 V, the IF buffer

output is 300 mVrms and when LOW GND, 1 mVrms or lower. Supports Sanyo’s LM7000 and LC7230.
