74AC138SCX Product Details

The AC/ACT138 is a high-speed 1-of-8 decoder/demultiplexer. This device is ideally suited for high-speed bipolar memory chip select address decoding. The multiple input enables allow parallel expansion to a 1-of-24 decoder using just three AC/ACT138 devices or a 1-of-32 decoder using four AC/ACT138 devices and one inverter.


  • ICC reduced by 50%
  • Demultiplexing capability
  • Multiple input enable for easy expansion
  • Active LOW mutually exclusive outputs
  • Outputs source/sink 24 mA
  • ACT138 has TTL-compatible inputs


  • This product is general usage and suitable for many different applications.
