Detailed Description
The 4040 IC is a versatile 12-stage binary ripple counter that operates across a wide range of supply voltages from 3V to 15V. It is part of the CMOS logic family, known for its low power consumption and high noise immunity. The IC features an asynchronous master reset, allowing the counter to be reset at any time. The clock input is edge-triggered, making it suitable for counting pulses in various applications such as frequency division, event counting, and time delay generation.
Pin Functions
- Reset (Pin 1): Asynchronous reset input that resets all stages of the counter when held high.
- Q12 to Q1 (Pins 2-7, 9-14): Outputs representing the binary count.
- Clock (Pin 15): Clock input used to advance the counter on the rising edge of the clock signal.
- Vdd (Pin 16): Positive supply voltage pin.
- Vss (Pin 8): Ground pin.
Electrical Characteristics
- Input Voltage High (Vih): 3.5V (Min) at Vdd=5V
- Input Voltage Low (Vil): 1.5V (Max) at Vdd=5V
- Output Voltage High (Voh): 4.95V (Min) at Vdd=5V, Io=-1µA
- Output Voltage Low (Vol): 0.05V (Max) at Vdd=5V, Io=1µA
