Overview

The VHC574 is an advanced high speed CMOS octal flip-flop with 3-STATE output fabricated with silicon gate CMOS 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 (CP) and an 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 0V to 7V 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.

  • This product is general usage and suitable for many different applications.
  • High Speed: tPD = 5.6 ns (typ) at VCC = 5V
  • High Noise Immunity: VNIH = VNIL = 28% VCC (Min)
  • Power Down Protection is provided on all inputs
  • Low Noise: VOLP = 0.6V (typ)
  • Low Power Dissipation: ICC = 4 µA (Max) @ TA = 25°C
  • Pin and Function Compatible with 74HC574
