CD40192BM CD40192BC Synchronous
4-Bit Up Down Decade Counter
CD40193BM CD40193BC Synchronous
4-Bit Up Down Binary Counter
General Description
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
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 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
All inputs are protected against damage due to static dis-
charge by clamps to VDD and VSS
Features
Y Wide supply voltage range
3V to 15V
Y High noise immunity
Y Low power TTL compatibility
0 45 VDD (typ )
Fan out of 2
driving 74L
or 1 driving 74LS
Y Carry and borrow outputs for easy expansion to N-bit
by cascading
Y Asynchronous clear
Y Equivalent to
MM54C192 MM74C192
and MM54C193 MM74C193

AC Parameters are guaranteed by DC correlated testing
Note 1 ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed They are not meant to imply that the devices
should be operated at these limits The table of ‘‘Recommended Operating Conditions’’ and ‘‘Electrical Characteristics’’ provides conditions for actual device
operation
Note 2 VSS e 0V unless otherwise specified
Note 3 IOH and IOL are tested one output at a time
Note 4 CPD determines the no load AC power consumption of any CMOS device For complete explanation see 54C 74C Family Characteristics application note
