MC100E016FNR2 is a high-performance presettable divide-by-N counter. It is intended for general pulse, frequency, and time applications. This versatile device can be used to divide by any integer from 1 to 32 and is available in a 16-pin narrow body plastic small outline (SO) package. It has an internal power-on reset circuit and is operational from 2.3 V to 5.5 V.

The MC100E016FNR2 has a pair of buffered D-type flip-flops and a 3-2 wired-OR decoder. The main application fields are digital systems, communication systems, automotive electronics, industrial, instrumentation and control systems, aerospace systems, air traffic control systems, home entertainment systems, office automation systems and scientific instruments.

The working principle of this device is based on the following features:

• The counter is composed of two sections: an up/down counter and 3-2 wired-OR decoder, which can be used to divide any number from 1 to 32. When the Enable pin is asserted, counting up will take place and when the Reset pin is asserted, the counter is reset to its preset value.

• The device has four cycle options: a single pulse option, a single cycle option, a multi-cycle option and a divide-by-N option. It can accept both rising and falling edge inputs up to 500 kHz and can operate up to 5.5 V.

• The reset pin is an active low input, which means it can be used to pre-load the counter with a known value. It is also used to reset the counter, in case a reset event is detected. This is useful for some applications, where the number of pulses is known in advance. Also, when the enable input is asserted, the output will remain in the same state until the enable input is de-asserted.

• The MC100E016FNR2 has two power pins: a power supply pin and a ground pin. The power supply should be used to supply power to the device, while the ground pin should be used to ground the other components in the circuit.

• The output of the device is asynchronous. This means that the output will remain in the same state even if the enable input is de-asserted. This is useful in applications, where the exact timing of the output is not required. The output can also be used as an interrupt line, which is helpful in some applications.

The MC100E016FNR2 can be used for a wide range of applications, including pulse counting, frequency dividing, time-delay generation and others. Its simple design, high speed and low power consumption make it an ideal choice for digital systems. It also comes with wide-ranging industrial and automotive compatibility, allowing for its use in automotive, industrial and scientific systems.
