Overview: ® 74LVQ74 DUAL D-TYPE FLIP FLOP WITH PRESET AND CLEAR s s s s s s s s s s s HIGH SPEED: fMAX = 250 MHz (TYP.) at VCC = 3.3V COMPATIBLE WITH TTL OUTPUTS LOW POWER DISSIPATION: ICC = 2 µA (MAX.) at TA = 25 oC LOW NOISE: VOLP = 0.2 V (TYP.) at VCC = 3.3V 75Ω TRANSMISSION LINE DRIVING CAPABILITY SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 12 mA (MIN) PCI BUS LEVELS GUARANTEED AT 24mA BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 3.6V (1.2V Data Retention) PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 74 IMPROVED LATCH-UP IMMUNITY M (Micro Package) T (TSSOP Package) ORDER CODES : 74LVQ74M 74LVQ74T 3.3V applications. A signal on the D INPUT is transferred to the Q OUTPUT during the positive going transition of the clock pulse. CLEAR and PRESET are independent of the clock and accomplished by a low setting on the appropriate input. It has better speed performance at 3.3V than 5V LSTTL family combined with the true CMOS low power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
