DESCRIPTION
The M74HC40103 is an high speed CMOS
8-STAGE
PRESETTABLE
SYNCHRONOUS
DOWN COUNTER fabricated with silicon gate
C2MOS technology.
The HC40103 consists of an 8 stage synchronous
down counter with a single output which is active
when the internal count is zero. The HC40103
contains a single 8-bit binary counter. This device
has control inputs for enabling or disabling the
clock, for clearing the counter to its maximum
count, and for presetting the counter either
synchronously or asynchronously. All control
inputs and the CARRY-OUT / ZERO DETECT
output are active low logic. In normal operation the
counter is decremented by one count on each
positive transition of the CLOCK. Counting is
inhibited when the CARRY-IN / COUNTER
ENABLE (CI/CE) input is high. The CARRY-OUT /
ZERO-DETECT (CO/ZD) output goes low when
the count reaches zero if the CI/CE input is low,
and remains low for one full clock period. When
the SYNCHRONOUS PRESET-ENABLE (SPE)
input is low, data at the J input is clocked into the
counter on the next positive clock transition
regardless of the state of the CI/CE input.
When the ASYNCHRONOUS PRESET-ENABLE
(APE) input is low, data at the J inputs is
asynchronously forced into the counter regardless
of the state of the SPE CI/CE or CLOCK inputs. J
input J0-J7 represent a singular 8-bit binary word.
When the CLEAR, CLR input is low, the counter is
asynchronously cleared to its maximum count
