AM27QBC/D09

LED Indication - Discrete

The AM27QBC/D09 is an 8-stage ripple carry binary counter from AMD Semiconductor. It is an integrated circuit that is made of metal-oxide-semiconductor (MOS) technology. This type of counter is commonly used in applications that require high speed counting. The AM27QBC/D09 counter is also capable of functioning in either binary or BCD output formations.

The AM27QBC/D09 counter is mainly utilized in LED indication, discrete counting, address generation, frequency division and other applications that require a ripple carry type of counter. The main functional blocks in the counter are the clock input, the ripple carry output and the inhibit input. The ripple carry output is one-out-of-eight output configurations allowing the counter to operate in binary or BCD outputs.

The AM27QBC/D09 counter features a fast ripple carry time. This means that the counter can count quickly but not in a uniform manner. If a uniform output is needed, then an external clock can be used to divide the outputs. The counter is also equipped with an asynchronous clear input and a synchronous reset, which can be used to reset the outputs when clock input is absent or stopped.

To employ the AM27QBC/D09 counter for LED indication or discrete counting, a clock signal must be applied to its CLK input (pins 11 and 12). The inhibit input of the counter can then be used to reset the output to a predetermined state. The output of the counter will then follow the clock input in either binary or BCD depending on the connections made. The clock input can be used to divide the output frequency. If the clock frequency is 1kHz, then the output frequency will be divided by 8, resulting in a 125Hz output.

The AM27QBC/D09 counter is also ideal for address generation. For this application, the clock input is connected to a special counter. The counter will then overflow with a certain pattern. This pattern is then used as the address for the targeted application. The same method can also be used for frequency division. When the counter reaches a certain count, it will provide an output. This output will then be used to drive the targeted application.

In conclusion, the AM27QBC/D09 IC is a useful IC for various applications. Its main function involves LED indication, discrete counting, address generation, and frequency division. The fast ripple carry time also makes it suitable for fast and accurate counting. With its multitude of features and applications, the AM27QBC/D09 IC is an extremely useful IC for many applications.
