Complementary TTL output

Comparator A latch enable. QA and

–

A are latched when LEA is high or floating.

Comparator A latch is transparent when LEA is low.

Comparator B latch enable. QB and

–

B are latched when LEB is high or floating.

Comparator B latch is transparent when LEB is low.

Latch enable. Q and

–

are latched when LE is TTL high or floating. The comparator latch is

transparent when LE is low.
