TC74ACT574F

TC74ACT574P/F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT574P, TC74ACT574F, TC74ACT574FT Octal D-Type Flip-Flop with 3-State Output The TC74ACT574 is an advanced high speed CMOS OCTAL FLIP-FLOP fabricated with silicon gate and double-layer metal wiring C2MOS 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. 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: fmax = 180 MHz (typ.) at VCC = 5 V Low power dissipation: ICC = 8 μA (max) at Ta = 25°C Compatible with TTL outputs: VIL = 0.8 V (max), VIH = 2.0 V (min) Symmetrical output impedance: |IOH| = IOL = 24 mA (min) Capability of driving 50 Ω transmission lines.
