Description
The Harris CD74HC4017 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 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.
