The internal circuit is composed of 3 stages (2
INPUT) or 5 stages (3 INPUT) including buffer
output, which enables high noise immunity and
stable output.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without

load. (R ef er to Test Circ ui t). Averag e operatin g current can be obtained by t he following equation. I
