TC74HC377AF(EL,F) Toshiba

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 2 TC74HC377AP FLIP-FLOP fabricated with silicon gate C MOS 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 TC74HC377AF discharge or transient excess voltage. Features High speed: f = 73 MHz (typ.) at V = 5 V max CC Low power dissipation: I = 4 A (max) at Ta = 25C CC High noise immunity: V = V = 28% V (min) NIH NIL CC Output drive capability: 10 LSTTL loads Symmetrical output impedance: I = I = 4 mA (min) OH OL Weight Balanced propagation delays: t t pLH pHL DIP20-P-300-2.54A : 1.30 g (typ.) Wide operating voltage range: V (opr) = 2 to 6 V CC SOP20-P-300-1.27A : 0.22 g (typ.)
