SL4017B
Counter/Divider
High-Voltage Silicon-Gate CMOS
The SL4017B 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.
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 in the SL4017B.

This device contains protection circuitry to guard against damage due to high static
voltages or electric fields. However, precautions must be taken to avoid applications of any
voltage higher than maximum rated voltages to this high-impedance circuit. For proper
operation, V
IN
and V
OUT
should be constrained to the range GND≤(V
IN
or V
OUT
)≤V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either
GND or V
CC
). Unused outputs must be left open.
