Description

The DS8673 and DS8674 products are low power prescalers which divide by 64 and 256 respectively. The devices are used in frequency synthesis applications such as TV/CATV, cellular phone, and instrumentation to divide a very high frequency down to a frequency usable by low power MOS PLL's.

The devices have differential buffered inputs and comple mentary ECL outputs. The inputs provide high input sensitivity and good isolation. The DS8673 is pin compatible with Plessey's SP4531, SP4632, and Motorola's MC12073 products. The DS8674 is pin compatible with Plessey's SP4653 and Motorola's MC12074 products.
