1 / 1 page CDC303 OCTAL DIVIDE-BY-2 CIRCUIT/CLOCK DRIVER SCAS323A – JULY 1990 – REVISED NOVEMBER 1995 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Replaces SN74AS303 D Maximum Output Skew Between Same Phase Outputs of 1 ns D Maximum Pulse Skew of 1 ns D TTL-Compatible Inputs and Outputs D Center-Pin VCC and GND Configurations Minimize High-Speed Switching Noise D Package Options Include Plastic Small-Outline (D) Package and Standard Plastic (N) 300-mil DIPs 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 (PRE) and clear (CLR) 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 tsk(o) and tsk(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.
