General Description
The CD40192BC and CD40193BC up/down counters are
monolithic complementary MOS (CMOS) integrated cir-
cuits. The CD40192BC is a BCD counter, while the
CD40193BC is a binary counter.
Counting up and counting down is performed 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” and a clear which forces all out-
puts to “0” when it is at logical “1”. The counters also have
carry and borrow outputs so that they can be cascaded
using no external circuitry.
All inputs are protected against damage due to static dis-
charge by clamps to V_DD and V_SS.
Features
s Wide supply voltage range: 3V to 15V
s High noise immunity: 0.45 V_DD (typ.)
s Low power TTL compatibility: Fan out of 2 driving 74L
or 1 driving 74LS
s Carry and borrow outputs for easy expansion to N-bit by
cascading
s Asynchronous clear
s Equivalent to: MM74C192 and MM74C193
