DESCRIPTION
The
HCC 40110B
(extended temperature range)
and
HCF40110B
(intermediate temperature range)
are monolithic integrated circuits, available in 16-
lead dual in-line plastic or ceramic package. The
HCC/HCF 40110B
is a dual-clocked up/down
counter with a special preconditioning circuit that
allows the counter to be clocked, via positive going
inputs, up ordown regardless of that state or timing
(within 100 ns typ.) of the other clock line. The clock
signal is fed into the control logic and Johnson
counter after is preconditioned. The outputs of the
Johnson counter (which include antilock gating to
avoid being locked at an illegal state) are fed intoa
latch. This data can be fed directly to the decoder
throughthelatch orcanbestrobedto hold aparticu-
lar count while theJohnson counter continues to be
clocked. The decoder feedsa seven-segment bipo-
lar output driver which can source up to 25 mA to
drive LEDs and other displays such as low-voltage
fluorescent and incandescent lamps. A short dura-
tionnegative-going pulse appearson theBORROW
output when the count changes from 0 to 9 or the
CARRY output when the count changes from 9 to
0.Atthe other timestheBORROWandCARRYout-
put are a logic 1. The CARRY and BORROW out-
puts can be tied directly to the clock-up and
clock-down lines respectively of another HCC/HCF
40110Bfor easy cascading of several counters.
