description

The CDC303 contains eight flip-flops designed to have low skew between outputs. The eight outputs (six in-phase with CLK and two out-of-phase) toggle on successive CLK pulses. Preset () and clear () inputs are provided to set the Q and Q\ outputs high or low independent of the clock (CLK) input.

The CDC303 has output and pulse-skew parameters t_sk(o) and t_sk(p) to ensure performance as a clock driver when a divide-by-two function is required.

The CDC303 is characterized for operation from 0°C to 70°C.
