description

The CD54HC4017 is a high-speed silicon-gate CMOS 5-stage Johnson counter with ten decoded outputs. Each

decoded output normally is low and sequentially goes high on the low-to-high transition of the clock (CP) input.

Each output stays high for one clock period of the ten-clock-period cycle. The terminal count (TC) output

transitions low to high after output ten (9) goes low, and can be used in conjunction with the clock enable (CE)

input to cascade several stages. CE disables counting when in the high state. The master reset (MR) input, when

taken high, sets all the decoded outputs, except 0, to low.

The CD54HC4017 is characterized for operation over the full military temperature range of –55°C to 125°C.
