DESCRIPTION
The HCC 40110B (extended temperature range)
andHCF 40110B(intermediate temperature range)
are monolithic integrated circuits, available in 16lead dual in-line plastic or ceramic package. The
HCC/HCF 40110B is a dual-clocked up/down
counter with a special preconditioning circuit that
allowsthecounter to be clocked, via positive going
inputs, up or down regardless of thatstateor timing
(within100 nstyp.) ofthe other clock line. Theclock
signal is fed into the control logic and Johnson
counter after is preconditioned. The outputs of the
Johnson counter (which include antilock gating to
avoidbeing locked at anillegal state) are fed intoa
latch. This data can be fed directly to the decoder
throughthelatch orcanbestrobedto hold aparticular count whilethe Johnson countercontinuesto be
clocked.The decoder feedsa seven-segment bipolar output driver which can sourceup to 25 mA to
driveLEDs andother displays such as low-voltage
fluorescent and incandescent lamps. A short durationnegative-going pulseappearson theBORROW
output when the count changes from 0 to 9 or the
CARRY output when the count changes from 9 to
0.Atthe other timestheBORROWandCARRYoutput are a logic 1. The CARRY and BORROW outputs can be tied directly to the clock-up and
clock-downlines respectively of another HCC/HCF
40110Bfor easycascading ofseveralcounters.
