CD74HC4017QPWREP
高速CMOS逻辑十进制计数器/除法器10解码输出 HIGH-SPEED CMOS LOGIC DECADE COUNTER/DIVIDER WITH 10 DECODED OUTPUTS
The CD74HC4017 is a high-speed silicon-gate 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.
