FAIRCHILD SEMICONDUCTOR 74VHC573M 芯片, 74VHC CMOS逻辑器件
The 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.
