| 1 || Q5 || The 6th sequential output

| 10 || Q4 || The 5th sequential output
|-
| 11 || Q9 || The 10th sequential output
|-
| 12 || CO || '''C'''arry '''o'''ut output - outputs high on counts 0 to 4, outputs low on counts 5 to 9 (thus a transition from low to high occurs when counting from 9 back to 0)
|-
| 13 || EN || Clock '''en'''able - inhibits the clock when high (i.e., the chip counts when EN is low)
|-
| 14 || CLK || '''Cl'''oc'''k''' in
|-
| 15 || MR || '''M'''aster '''R'''eset - sets outputs Q0 and CO high and outputs Q1 through Q9 low, when taken high
|-
| 16 || V<sub>DD</sub> || The connection to the +V rail (voltage between +3&nbsp;V and +18&nbsp;V)
