It achieves the high speed operation similar to equivalent LSTTL while maintaining the C2MOS low power dissipation. The signal level applied to the D INPUT is transferred to Q OUTPUT during the positive going transition of the CLOCK pulse CLEAR and PRESET are independent of the CLOCK and are accomplished by setting the appropriate input to an “L” level Input is equipped with protection circuits against static discharge or transient excess voltage. Features • High speed: fMAX = 77 MHz typ. at VCC = 5 V • Low power dissipation: ICC = 2 μA max at Ta = 25°C • High noise immunity: VNIH = VNIL = 28% VCC min • Output drive capability: 10 LSTTL loads • Symmetrical output impedance: |IOH| = IOL = 4 mA min • Balanced propagation delays: tpLH −∼ tpHL • Wide operating voltage range: VCC opr = 2 to 6 V
