The enable inputs were implemented in this way

because they are intended to be driven directly by

a microprocessor. Currently available microproces-

sors may generates spikes as high as 1.5 V during

power-up. These inputs may be used for a variety

of applications such as motor inhibit during reset of

the logical system and power-on reset (see fig. 3).
