TC74ACT574P/F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT574P, TC74ACT574F, TC74ACT574FT Octal D-Type Flip-Flop with 3-State Output TC74ACT574P The TC74ACT574 is an advanced high speed CMOS OCTAL FLIP-FLOP fabricated with silicon gate and double-layer metal 2 wiring C MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This devices may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are compatible with TTL, NMOS and CMOS output voltage levels. TC74ACT574F These 8-bit D-type flip-flops are controlled by a clock input (CK) and a output enable input ( OE ). When the OE input 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: f = 180 MHz (typ.) at V = 5 V max CC TC74ACT574FT Low power dissipation: I = 8 A (max) at Ta = 25C CC Compatible with TTL outputs: V = 0.8 V (max), V = 2.0 V (min) IL IH Symmetrical output impedance: I = I = 24 mA (min) Capability of driving 50 OH OL transmission lines. Balanced propagation delays: t t pLH pHL Pin and function compatible with 74F574 Weight DIP20-P-300-2.54A : 1.30 g (typ.) SOP20-P-300-1.27A : 0.22 g (typ.) TSSOP20-P-0044-0.65A : 0.08 g (typ.)
