74LCX32 4/11 table 8: ac electrical characteristics 1) skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs of the same device switch- ing in the same direction, either high or low (t oslh = | t plhm - t plhn |, t oshl = | t phlm - t phln |) 2) parameter guaranteed by design table 9: capacitive characteristics 1) c pd 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. i cc(opr) = c pd x v cc x f in + i cc /4 (per gate) figure 3: test circuit c l = 50 pf or equivalent (includes jig and probe capacitance) r l = 500 ? or equivalent r t = z out of pulse generator (typically 50 ? ) symbol parameter test condition value unit v cc (v) c l (pf) r l ( ? ) t s = t r (ns) -40 to 85 c -55 to 125 c min. max. min. max. t plh t phl propagation delay time 2.7 50 500 2.5 6.0 6.9 ns 3.0 to 3.6 1.0 5.2 6.0 t oslh t oshl output to output skew time (note1, 2) 3.0 to 3.6 50 500 2.5 1.0 1.0 ns symbol parameter test condition value unit v cc (v) t a = 25 c min. typ. max. c in input capacitance 3.3 v in = 0 to v cc 5pf c pd power dissipation capacitance (note 1) 3.3 f in = 10mhz v in = 0 or v cc 41 pf www.datasheet www.datasheet www.datasheet www.datasheet 4u 4u4u 4u .com .com .com .com 4 .com u datasheet
