TC74LVX138F/FN/FT
3-to-8 Line Decoder
TC74LVX138F/ high-speed CMOS 3-to-8 line decoder fabricated with silicon gate CMOS technology. Designed systems, achieves high-speed operation while maintaining CMOS power dissipation. This device suitable low-voltage battery operated systems. When device enabled, Binary Select inputs determine which outputs (Y0-Y7) will low. When enable input held either held high, decoding function inhibited outputs high. G2A, inputs provided ease cascade connection address decoder memory systems. input protection circuit ensures that 5.5V applied input pins without regard supply voltage. This device used interface systems supply systems such battery back This circuit prevents device destruction mismatched supply input voltages.
