TC74LVX273F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LVX273F, TC74LVX273FT Octal D-Type Flip-Flop with Clear TC74LVX273F The TC74LVX273F/ FT is a high-speed CMOS octal D-flip flop fabricated with silicon gate CMOS technology. Designed for use in 3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. This device is suitable for low-voltage and battery operated systems. Information signals applied to D inputs are transferred to the Q outputs on the positive going edge of the clock pulse. When the CLR input is held low, the Q outputs are in the low logic level independent of the other inputs. TC74LVX273FT An input protection circuit ensures that 0 to 5.5V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.
