DESCRIPTION

The HCC 40110B (extended temperature range)

and HCF 40110B (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 or down 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 into a

latch. This data can be fed directly to the decoder

through the latch or can be strobed to hold a particu-

lar count while the Johnson counter continues to be

clocked. The decoder feeds a 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-

tion negative-going pulse appears on the BORROW

output when the count changes from 0 to 9 or the

CARRY output when the count changes from 9 to

0. At the other times the BORROW and CARRY out-

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

40110B for easy cascading of several counters.
