74VHCT138AFT(BJ)

74VHCT138AFT(BJ) is a CMOS digital silicon monolithic IC. It is an advanced high speed CMOS 3-to-8 line decoder fabricated with silicon gate C²MOS technology. It achieves the high speed operation similar to equivalent bipolar schottky TTL while maintaining the CMOS low power dissipation. The input voltage is compatible with TTL output voltage. This device may be used as a level converter for interfacing 3.3V to 5V system. Input protection and output circuit ensure that 0 to 5.5V can be applied to the input and output (Note) pins without regard to the supply voltage. This structure prevents device destruction due to mismatched supply and input/output voltages such as battery back-up, hot board insertion, etc.
