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 (tOSLH = | tPLHm - tPLHn|, tOSHL = | tPHLm - tPHLn|)

2) Parameter guaranteed by design

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/6 (per gate)

TEST CIRCUIT

CL = 50pF or equivalent (includes jig and probe capacitance)

RL = 500Ω or equivalent

RT = ZOUT of pulse generator (typically 50Ω)
