AC Electrical Characteristics (Note 4)

TA = 25°C, CL = 50 pF, RL = 200k, Input tr = tf = 20 ns, unless otherwise noted

Note 4: AC Parameters are guaranteed by DC correlated testing.

Note 5: Dynamic power dissipation (PD) is given by: PD = (CPD + CL) VCC

2f

+ P

Q; where CL = load capacitance; f = frequency of operation; for further details,

see application note AN-90, “54C/74C Family Characteristics”.
