1 / 8 page © 2005 Fairchild Semiconductor Corporation DS011565 www.fairchildsemi.com March 1993 Revised May 2005 74VHC574 Octal D-Type Flip-Flop with 3-STATE Outputs General Description 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 volt- age. This device can be used to interface 5V to 3V systems and two supply systems such as battery back up. This cir- cuit prevents device destruction due to mismatched supply and input voltages. Features s High Speed: tPD 5.6 ns (typ) at VCC 5V s High Noise Immunity: VNIH VNIL 28% VCC (Min) s Power Down Protection is provided on all inputs s Low Noise: VOLP 0.6V (typ) s Low Power Dissipation: ICC 4 PA (Max) @ TA 25qC s Pin and Function Compatible with 74HC574 Ordering Code: Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering code. Pb-Free package per JEDEC J-STD-020B.
