The internal circuit is composed of 3-stage
including buffered output, which gives 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. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/2 (per gate)
TEST CIRCUIT
CL = 50pF or equivalent (includes jig and probe capacitance)
RT = ZOUT of pulse generator (typically 50Ω)
