The CLOCK ENABLE input disables counting The M74HC4017 is a 5-stage Johnson counter when in the high state. A CLEAR (CLR) input is with 10 decoded outputs. Each of the decoded also provided which when taken high sets all the outputs is normally low and sequentially goes high decoded outputs low. on the low to high transition of the clock input. All inputs are equipped with protection circuits Each output stays high for one clock period of the against static discharge and transient excess 10 clock period cycle. The CARRY output goes voltage. low to high after OUTPUT 10 goes low, and can PIN CONNECTION AND IEC LOGIC SYMBOLS August 2001 1/12 Obsolete Product(s) - Obsolete Product(s)M74HC4017 INPUT AND OUTPUT EQUIVALENT CIRCUIT PIN DESCRIPTION PIN No SYMBOL NAME AND FUNCTION 3, 2, 4, 7, 10, Q0 to Q9 Decoded Outputs 1, 5, 6, 9, 11 Carry Output C 12 OUT (Active LOW) Clock Enable Input 13 CKEN (Active LOW) Clock Input (LOW to 14 CLOCK HIGH, Edge Triggered) Master Reset Inputs 15 CLEAR (Active HIGH) 8 GND Ground (0V) 16 Vcc Positive Supply Voltage TRUTH TABLE CLOCK CLOCK ENABLE CLEAR DECODED OUTPUT(H) XX H QO LXL Qn XH L Qn L L Qn + 1 LL Qn HLQn H L Qn + 1 X : Dont Care Qn : No Change LOGIC DIAGRAM This logic diagram has not be used to estimate propagation delays 2/12 Obsolete Product(s) - Obsolete Product(s)
