74VHC138MX datasheet



The VHC138 is an advanced high speed CMOS 3-to-8 decoder/demultiplexer 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 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.
