outputs. 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.
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 configuration 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 IW4017B.
The IW4017B is 5-stage Johnson counter having 10 decoded
The counter is advanced one count at the positive clock signal
