TC74HCT374AF(F)

TC74HCT374AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HCT374AP, TC74HCT374AF Octal D-Type Flip-Flop with 3-State Output The TC74HCT374A is high speed CMOS OCTAL FLIP-FLOP 2 TC74HCT374AP with 3-STATE OUTPUT fabricated with silicon gate C MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Their inputs are compatible with TTL, NMOS, and CMOS output voltage levels. This 8-bit D-type flip-flop is controlled by a clock input (CK) and an output enable input ( OE ). All inputs are equipped with protection circuits against static discharge or transient excess voltage. TC74HCT374AF Features High speed: f = 62 MHz (typ.) at V = 5 V max CC Low power dissipation: I = 4 A (max) at Ta = 25C CC Compatible with TTL outputs: V = 2 V (min) IH V = 0.8 V (max) IL Wide interfacing ability: LSTTL, NMOS, CMOS Output drive capability: 15 LSTTL loads Weight Symmetrical output impedance: I = I = 6 mA (min) OH OL DIP20-P-300-2.54A : 1.30 g (typ.)
