Note 1 Conditions for testing not shown in the Table are chosen to guarantee operation under ‘‘worst case’’ conditions
Note 2 The specified limits represent the ‘‘worst case’’ value for the parameter Since these ‘‘worst case’’ values normally occur at the temperature and supply
voltage extremes additional noise immunity and guard banding can be achieved by decreasing the allowable system operating ranges
Note 3 Typical limits are at V
Note 4 The M
reference as in normal TTL practice effectively makes the threshold vary directly with V
signal swing about threshold of
required V
Note 5 TTL Output Signal swing is guaranteed at f
