TOSHIBA TC74ACT574FTEL

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(overline) 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.

• High speed: f(max)=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
• Balanced propagation delays: t(pLH) ≃ t(pHL)
• Pin and function compatible with 74F574
