counter reaches its maximum count in the UP mode
or the minimum count in the DOWN mode provided
the CARRY-IN signal is low. The CARRY-IN signal
in the low state can thus be considered a CLOCK
ENABLE. The CARRY-IN terminal must be con-
nected to V
complished when the BINARY/DECADE input is
high ; the counter counts in the decade mode when
the BINARY/DECADE input is low. The counter

ABSOLUTE MAXIMUM RATING
Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress ratingonly and functional
operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure
to absolute maximum rating conditions for external periods may affect device reliability.

counts Up when to UP/DOWN INPUT is high, and
Down when the UP/DOWN INPUT is low. Multiple
packages can be connected in either a parallel-
clocking or a ripple-clocking arrangement as shown
in cascading counter packages. Parallel clocking
provides synchronous control and hence faster re-
sponse from all counting outputs. Ripple-clocking
allows for longer clock input rise and fall times.
