Information at the D input is transferred to the Q and Q outputs on the positive-going edge of the clock pulse. All four flip-flops are controlled by a common clock (CP) and a common reset (MR). Resetting is accomplished by a LOW logic level independent of the clock. * Typical Propagation Delay - 6.4ns at VCC = 5V, TA = 25oC, CL = 50pF * Exceeds 2kV ESD Protection MIL-STD-883, Method 3015 * SCR-Latchup-Resistant CMOS Process and Circuit Design Ordering Information * Speed of Bipolar FASTTM/AS/S with Significantly Reduced Power Consumption PART NUMBER * Balanced Propagation Delays * AC Types Feature 1.5V to 5.5V Operation and Balanced Noise Immunity at 30% of the Supply * 24mA Output Drive Current - Fanout to 15 FASTTM ICs - Drives 50 Transmission Lines TEMP.
