CD40192BM/CD40192BC Synchronous
4-Bit Up/Down Decade Counter
CD40193BM/CD40193BC Synchronous
4-Bit Up/Down Binary Counter
General Description
Features
Y
Wide supply voltage range
3V to 15V
0.45 V (typ.)
These up/down counters are monolithic complementary
MOS (CMOS) integrated circuits. The CD40192BM and
CD40192BC are BCD counters, while the CD40193BM and
CD40193BC are binary counters.
Y
High noise immunity
DD
Y
Low power TTL compatibility
Fan out of 2
driving 74L
or 1 driving 74LS
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.
Y
Carry and borrow outputs for easy expansion to N-bit
by cascading
Y
Y
Asynchronous clear
These counters feature preset inputs that are enabled when
load is a logical ‘‘0’’ and a clear which forces all outputs 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.
Equivalent to
MM54C192/MM74C192
and MM54C193/MM74C193
All inputs are protected against damage due to static dis-
.
