74VHC573M Datasheet PDF - Fairchild

●The 74VHC573M is an octal high speed CMOS D Latch with 3-state outputs. It is 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 latch is controlled by a LE and an OE\\. When the OE\ input is high, the eight outputs are in a high impedance state. An input protection circuit ensures that 0 to 7V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 to 3V systems and two supply systems such as battery back-up. This circuit prevents device destruction due to mismatched supply and input voltages.

● Power down protection is provided on all inputs

● High noise immunity

● Low power dissipation

● Pin and function compatible with 74HC573
