The SN74HC4040N is an integrated circuit (IC) component designed for high-speed binary ripple counter applications. It is a 12-stage counter/divider with an internal oscillator and reset input, allowing it to be used as a frequency divider.
The key features of the SN74HC4040N include:
1. High-speed operation: The IC can operate at speeds of up to 42 MHz, making it suitable for applications that require high-frequency counting or division.
2. 12-stage binary ripple counter: The IC consists of 12 flip-flops connected in a ripple counter configuration. Each flip-flop divides the input frequency by two, resulting in a total division factor of 2^12 or 4096.
3. Internal oscillator: The IC includes an internal oscillator that can generate clock signals for counting operations. The oscillator uses an external resistor and capacitor to set the desired frequency and can be enabled or disabled using the control inputs.
4. Asynchronous reset input: The IC features an asynchronous reset input (RST) that allows the counter to be reset to its initial state. When a high voltage is applied to the RST pin, the counter is asynchronously reset to zero.
5. Buffered outputs: The 12 counter outputs (Q0-Q11) are buffered and can drive high-capacitive loads without significant degradation in performance.
6. Schmitt-trigger inputs: The IC has Schmitt-trigger inputs, which provide hysteresis and improved noise immunity
