12V 5MHz COUNTER

The portable counter is designed with low-power logic to minimize battery drain while maintaining good performance. Since most of the milliwatt power drain is consumed by the digital readout, the circuit blanks the LED display when there is no input signal. The time base divides the 1-MHz crystal oscillator frequency down to the desired enable time, up to tOs, using a 31/2 MC14518 dual decade counter.

The portable counter circuit utilizes a low-power logic design, which is crucial for extending battery life in portable applications. The primary component, a 1-MHz crystal oscillator, serves as the time base for the counter, ensuring accurate timing and frequency division. The MC14518 dual decade counter is employed to divide the oscillator frequency down to the desired output frequency, which can be configured to various enable times, allowing for flexibility in operation.

The design includes a digital readout that displays the counted values. To conserve power, the LED display is automatically turned off when there is no input signal, significantly reducing the overall power consumption during idle periods. This feature is particularly beneficial in battery-operated devices where energy efficiency is paramount.

The circuit layout incorporates necessary support components, such as capacitors for filtering and resistors for biasing, ensuring stable operation of the oscillator and counter. The use of low-power components throughout the design further enhances the efficiency of the circuit, making it suitable for various portable applications where battery life is critical.

Overall, the portable counter circuit combines efficient power management with reliable performance, making it an ideal solution for applications requiring accurate counting and timing in a compact form factor.Portable counter is designed with low-power logic to minimize battery drain, yet provides good performance.Since most of milliwatt power drain is taken by digital readout, circuit blanks out LED display when there is no input signal.
