NO SEL UNDER HIGH LET HEAVY IONS
IRRADIATION
The device requires the 3-STATE control input G
to be set high to place the output into the high
impedance state.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

1) C is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
PD
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. I
= C x V x f + I /4 (per buffer)
