The HEC4040BT,112 is a high-speed, low power consumption programmable counter/divider with five operating modes.

The HEC4040BT,112 provides five operating modes as standard: Frequency Divider, Pulse/Edge Counter, Frequency Ratio Counter, Time Division Counter and Combination Counter. Each mode has its own unique features and design considerations.

In Frequency Divider mode, the HEC4040BT,112 can divide the input frequency by any integer from 1 to 16. The divider is programmable per channel, allowing multiple channels to be used with different dividing ratios. The divider can also be used to divide down frequencies from an external source, such as an oscillator, or from a clock in the system. This mode is well suited for applications such as motor speed control and motor speed measurement.

In Pulse/Edge Counter mode, the HEC4040BT,112 counts the pulses generated by an external sensor, such as a photocell or magnetic reed switch. This is useful in applications such as automotive speed sensors or process control. The counter also has a polarity detection feature that allows it to distinguish between rising and falling edges of the input signal. This allows the counter to be used with high speed signals, such as switch closure type signals.

In Frequency Ratio Counter mode, the HEC4040BT,112 counts the ratio between the input frequency and another signal such as a reference clock. This allows the counter to be used in applications such as frequency modulation and demodulation, as well as for pulse repetition rate measurements.

The Time Division Counter mode allows multiple channels to be used in sequence. This is useful for applications such as analog-to-digital conversion. This mode also allows the counter to be used as an interval timer. The counter can be programmed to count the absolute time of day and provide a signal when a scheduled time is reached.

The Combination Counter mode allows multiple counter/divider channels to be combined into a single unit. This mode is useful for more complex count and divide applications, such as analog-to-digital measurements, frequency modulation/demodulation, and pulse repetition rate measurements. It also allows the user to monitor multiple channels at the same time.

The HEC4040BT,112 features a wide operating temperature range, low power consumption, and programmable functions. These features make the HEC4040BT,112 an ideal choice for counting and dividing applications in many electronic systems.
