GENERAL DESCRIPTlON - The 11C83 Prescaler is guaranteed to operate above 950 MHz over the OoC to +750C temperature range and with a VCC variation from +4.75 to +5.5 V. The circuit requires only one supply voltage and the clock input signal can be either dc or ac coupled. The prescaler divides by either 248 0r 256, as determined by the signal applied to the Mode Control (MJ input. This feature makes it possible to use the 11C83 in conjunction with other logic to achieve a broad range of overall divide ratios, either fixed or programmable. For example, a divide ratio of 1000 can be achieved by one 11C83 and one 9LS161 modulo-16 counter.
