Part Details:

74LCX74 Low voltage CMOS dual D-Type Flip Flop with 5V tolerant inputs Features 5V tolerant inputs High speed: ­ fMAX = 150MHz (Max) at VCC = 3V Power down protection on inputs and outputs Symmetrical output impedance: SO-14 TSSOP14 ­ |IOH| = IOL = 24mA (Min) at VCC = 3V PCI bus levels guaranteed at 24mA Description Balanced propagation delays: ­ tPLH tPHL The 74LCX74 is a low voltage CMOS dual D-type Operating voltage range: flip flop with preset and clear non inverting fabricated with sub-micron silicon gate and ­ VCC (Opr) = 2.0V to 3.6V double-layer metal wiring C2MOS technology. It is Pin and function compatible with ideal for low power and high speed 3.3V 74 series 74 applications; it can be interfaced to 5V signal Latch-up performance exceeds environment for inputs. 500mA (JESD 17) A signal on the D INPUT is transferred to the Q ESD performance: OUTPUT during the positive going transition of ­ HBM > 2000V the clock pulse. (MIL STD 883 method 3015); MM > 200V CLR and PR are independent of the clock and accomplished by a low setting on the appropriate input. It has same speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
