TC74VHC574FW

TC74VHC574F/FW/FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC574F,TC74VHC574FW,TC74VHC574FT,TC74VHC574FK Octal D-Type Flip Flop with 3-State Output The TC74VHC574 is advanced high speed CMOS OCTAL FLIP-FLOP with 3-STATE OUTPUT fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This 8-bit D-type flip-flop is 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. An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages. Features High speed: fmax = 180 MHz (typ.) at VCC = 5 V Low power dissipation: ICC = 4 µA (max) at Ta = 25°C High noise immunity: VNIH = VNIL = 28% VCC (min) Power down protection is provided on all inputs. Balanced propagation delays: tpLH ∼− tpHL Wide operating voltage range: VCC (opr) = 2 to 5.5 V Low noise: VOLP = 1.2 V (max) Pin and function compatible with 74ALS574 Note: xxxFW (JEDEC SOP) is not available in Japan.
