N74F138D – Fast, Expandable 1-of-8 Decoder/Demux

The N74F138D delivers quick, reliable decoding in a compact SOIC-16 package. It takes three address inputs (A0, A1, A2) and gives eight mutually exclusive, active-LOW outputs. It includes three enable inputs—two active LOW, one active HIGH—for easy cascading or expansion to larger decoders. It runs on a 4.5–5.5 V supply and fits standard surface-mount assembly. Designers trust it for memory chip-select logic, thanks to its predictable behaviour and flexibility. Ready to order or need more specs? Click to check availability and get it into your design.
