TECHNICAL DATA

KK4017B

Counter/Divider

The KK4017B is 5-stage Johnson counter having 10 decoded 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.

N SUFFIX

PLASTIC

The counter is 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 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.
