TC74HC377AF

TC74HC377AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC377AP, TC74HC377AF Octal D-Type Flip-Flop The TC74HC377A is a high speed CMOS OCTAL D-TYPE FLIP-FLOP fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. This 8-bit D-type flip-flop is controlled by a clock input (CK) and an output enable input ( G ). The signal level applied to the D inputs are transferred to Q outputs during the positive going transition of CK. When the G is high, the eight outputs are in a high impedance state. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Features High speed: fmax = 73 MHz (typ.) at VCC = 5 V Low power dissipation: ICC = 4 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 Pin and function compatible with 74LS377 Pin Assignment TC74HC377AP TC74HC377AF Weight DIP20-P-300-2.54A SOP20-P-300-1.27A : 1.30 g (typ.) : 0.22 g (typ.)
