IC 4060 Pin Functions
Let’s delve into the functions of each pin of the IC 4060:
Power Supply Pins (VDD and VSS)
- Pin 14 (VDD): This pin is the positive supply voltage input. It should be connected to the positive power supply, typically ranging from 3V to 15V, depending on the specific IC 4060 variant.
- Pin 8 (VSS): This pin is the ground or negative supply voltage input. It should be connected to the ground or negative power supply of the circuit.
Clock Input (CLK_IN)
- Pin 13 (CLK_IN): This pin is the clock input of the IC 4060. It accepts an external clock signal that triggers the counter to increment on each rising edge of the clock. The maximum clock frequency depends on the supply voltage and the specific IC variant.
Reset Input (RS)
- Pin 12 (RS): This pin is the active-low reset input. When this pin is pulled low (connected to ground), it resets the counter to its initial state (all outputs become low). When the reset pin is high (connected to VDD or left floating), the counter operates normally.
Counter Outputs (Q3 to Q14)
- Pins 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 15, 16 (Q3 to Q14): These pins are the counter outputs of the IC 4060. Each output represents a specific stage of the 14-stage ripple carry binary counter. The outputs are labeled from Q3 to Q14, with Q3 being the least significant bit (LSB) and Q14 being the most significant bit (MSB). The outputs toggle at different frequencies based on their position in the counter chain.
The following table shows the relationship between the counter outputs and their respective frequencies:
| Counter Output | Frequency |
|---|---|
| Q3 | CLK_IN ÷ 8 |
| Q4 | CLK_IN ÷ 16 |
| Q5 | CLK_IN ÷ 32 |
| Q6 | CLK_IN ÷ 64 |
| Q7 | CLK_IN ÷ 128 |
| Q8 | CLK_IN ÷ 256 |
| Q9 | CLK_IN ÷ 512 |
| Q10 | CLK_IN ÷ 1024 |
| Q11 | CLK_IN ÷ 2048 |
| Q12 | CLK_IN ÷ 4096 |
| Q13 | CLK_IN ÷ 8192 |
| Q14 | CLK_IN ÷ 16384 |
