Part Details:

74VHC74 DUAL D-TYPE FLIP FLOP WITH PRESET AND CLEAR s HIGH SPEED: fMAX = 170 MHz (TYP.) at VCC = 5V s LOW POWER DISSIPATION: ICC = 2 µA (MAX.) at TA=25°C s HIGH NOISE IMMUNITY:VNIH = VNIL = 28% VCC (MIN.) SOP TSSOP s POWER DOWN PROTECTION ON INPUTS s SYMMETRICAL OUTPUT IMPEDANCE:|IOH| = IOL = 8 mA (MIN) Table 1: Order Codes s BALANCED PROPAGATION DELAYS:t PACKAGE T & R PLH tPHL s OPERATING VOLTAGE RANGE: SOP 74VHC74MTR VCC(OPR) = 2V to 5.5V TSSOP 74VHC74TTR 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 74VHC74 is an advanced high-speed CMOS and 0 to 7V can be accepted on inputs with no DUAL D-TYPE FLIP FLOP WITH PRESET AND regard to the supply voltage. This device can be CLEAR fabricated with sub-micron silicon gate used to interface 5V to 3V. and double-layer metal wiring C2MOS 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 OUTPUTS during the positive going transition of them 2KV ESD immunity and transient excess the clock pulse. voltage.
