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 configuration permits high−speed operation, 2−input decode−gating, and spike−free decoded outputs.
