General Description

The CD40192BC and C D40193BC up/down counte rs are
monolithic complementary MOS (CMOS) integrated cir­cuits. The CD40192BC is a BCD counter, while the
CD40193BC is a binary counter.

Counting up and countin g down is perfor med by two count
inputs, one being held HIGH while the other is clocked. The
outputs change on the positive-going transition of this
clock.

These counters feature preset inputs that are enabled

when load is a logical “0” an d a clear which forces all out­puts to “0” when it is a t logi cal “1 ”. Th e coun ters a lso have
carry and borrow outputs so that they can be cascaded
using no external circuitry.

All inputs are protected a gainst damage due to stati c dis­charge by clamps to V

and VSS.
