ON Semiconductor MC14520BDWR2G Dual Binary Up Counter
The MC14520BDWR2G from ON Semiconductor is a high-quality integrated circuit that serves as a dual binary up counter, designed to offer precision and reliability for a wide range of digital applications. This device is part of ON Semiconductor's extensive CMOS logic family and exhibits the robust performance characteristics associated with this technology.
Constructed using P-channel and N-channel enhancement mode devices in a single monolithic structure, the MC14520BDWR2G provides a symmetrical output drive with the capability of both sourcing and sinking current. This feature ensures that the device can interact with a variety of other components within a digital system without the need for additional interfacing hardware.
The counter advances on the falling edge of the clock signal, which makes it suitable for precision timing applications where the timing of the signal's negative transition is critical. Each of the two counters within the IC has a separate clock input to enable independent operation, and both share a common reset line. The reset input is active high and, when asserted, will set all outputs to a low state, effectively resetting the counter.
The MC14520BDWR2G operates over a wide voltage range from 3 V to 18 V, making it versatile for use in both TTL and CMOS circuits. This wide operating range also allows the device to be used in battery-operated applications where power supply levels may vary.
Packaged in a 16-pin SOIC package, the device is designed for surface-mount technology, which is beneficial for modern, space-constrained electronic assemblies. The compact form factor of the SOIC package allows for efficient use of PCB real estate, while also providing the thermal and electrical performance required for reliable operation.
In summary, the MC14520BDWR2G from ON Semiconductor is a dependable and flexible solution for designers looking to implement a binary up counter in their digital systems. Its compatibility with various voltage levels, combined with the efficiency of a CMOS design, makes it an excellent choice for applications ranging from automation, instrumentation, to consumer electronics.
