The ’HC4017 is a high speed silicon gate CMOS 5-stage
Johnson counter with 10 decoded outputs. Each of the
decoded outputs is normally low and sequentially goes high
on the low to high transition clock period of the 10 clock
period cycle. The CARRY (TC) output transitions low to high
after OUTPUT 10 goes from high to low, and can be used in
conjunction with the CLOCK ENABLE (CE) to cascade
several stages. The CLOCK ENABLE input disables
counting when in the high state. A RESET (MR) input is also
provided which when taken high sets all the decoded
outputs, except “0”, low.
The device can drive up to 10 low power Schottky equivalent
loads.
