The CD74HC4017 is a high-speed silicon-gate
GND 8
98
CMOS 5-stage Johnson counter with ten decoded
outputs. Each of the decoded outputs normally is low
and sequentially goes high on the low-to-high transition clock period of the ten-clock-period cycle. The carry
(TC) output transitions low to high after output 9 goes from high to 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. A master reset
(MR) input also is provided that, when taken high, sets all the decoded outputs, except output 0, to low.
The device can drive up to ten low-power Schottky equivalent loads.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltages referenced to GND unless otherwise specified.
2. The package thermal impedance is calculated in accordance with JESD 51-7.
