Table 7: AC Electrical Characteristics (Input tr = tf = 3ns)

(*) Voltage range is 3.3V

± 0.3V

(**) Voltage range is 5.0V

± 0.5V

Note 1: Parameter guaranteed by design. tsoLH = |tpLHm - tpLHn|, tsoHL = |tpHLm - tpHLn|

Table 8: Capacitive Characteristics

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/8 (per circuit)
