74v2t74 5/13 capacitive characteristics 1) c pd is defined as the value of the ics 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. i cc(opr) = c pd x v cc x f in + i cc test circuit c l =15/50pf or equivalent (includes jig and probe capacitance) r t = z out of pulse generator (typically 50 w ) symbol parameter test condition value unit v cc (v) t a = 25c -40 to 85c -55 to 125c min. typ. max. min. max. min. max. c in input capacitance 5.0 4101010pf c pd power dissipation capacitance (note 1) 5.0 f in = 10mhz 22 pf
