NTE4017B & NTE4022B
Integrated Circuit
CMOS, Counter/Divider
Description:
The NTE4017B and NTE4022B are 5−stage and 4−stage Johnson counters in 16−Lead DIP type
packages having 10 and 8 decoded outputs, respectively. Inputs include a CLOCK, a RESET, and
a CLOCK INHIBIT signal. Schmitt trigger action in the CLOCK input circuit provides pulse shaping
that allows unlimited clock input pulse rise and fall times.
These counters are advanced one count at the positive clock signal transition if the CLOCK INHIBIT
signal is low. Counter advancement via the clock line is inhibited when the CLOCK INHIBIT signal
is high. A high RESET signal clears the counter to its zero count. Use of the Johnson counter configu-
ration permits high−speed operation, 2−input decode−gating, and spike−free decoded outputs. Anti−
lock gating is provided, thus assuring proper counting sequence. The decoded outputs are normally
low and go high only at their respective decoded time slot. Each decoded output remains high for
one full clock cycle. A CARRY−OUT signal completes one cycle every 10 clock input cycles in the
NTE4017B or every 8 clock input cycles in the NTE4022B and is used to ripple−clock the succeeding
device in a multi−device counting chain.
