Part Details:

74VHCT74A DUAL D-TYPE FLIP FLOP WITH PRESET AND CLEAR s HIGH SPEED: fMAX = 160 MHz (TYP.) at VCC = 5V s LOW POWER DISSIPATION:ICC = 2 µA (MAX.) at TA=25°C s COMPATIBLE WITH TTL OUTPUTS:VIH = 2V (MIN.), VIL = 0.8V (MAX) s POWER DOWN PROTECTION ON INPUTS SOP TSSOP & OUTPUTS s SYMMETRICAL OUTPUT IMPEDANCE: Table 1: Order Codes |IOH| = IOL = 8 mA (MIN) s BALANCED PROPAGATION DELAYS: PACKAGE T & R tPLH tPHL SOP 74VHCT74AMTR s OPERATING VOLTAGE RANGE:V TSSOP 74VHCT74ATTR CC(OPR) = 4.5V to 5.5V s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 74 CLR and PR are independent of the clock and s IMPROVED LATCH-UP IMMUNITY accomplished by a low setting on the appropriateinput. DESCRIPTION Power down protection is provided on all inputs The 74VHCT74A is an advanced high-speed and outputs and 0 to 7V can be accepted on CMOS DUAL D-TYPE FLIP FLOP WITH PRESET inputs with no regard to the supply voltage. This AND CLEAR fabricated with sub-micron silicon device can be used to interface 5V to 3V since all gate and double-layer metal wiring C2MOS inputs are equipped with TTL threshold. technology. All inputs and outputs are equipped with A signal on the D INPUT is transferred to the Q protection circuits against static discharge, giving OUTPUT during the positive going transition of the them 2KV ESD immunity and transient excess clock pulse. voltage.
