- **Latch-Up Performance:** Exceeds 100 mA per JESD 78  
- **ESD Protection:** HBM > 2000V, CDM > 1000V  
- **Small Package:** SOT-23-8 (DCU) for space-constrained applications

Application Scenarios & Design Considerations

2-Line-to-4-Line Decoder

Alternative Part Number

  • 74LVC1G139GW,125 --: Same single 2-to-4 line decoder/demultiplexer function in LVC family, different manufacturer and package naming, widely available.
  • NC7SZ139P5X --: TinyLogic single 2-to-4 decoder with equivalent logic function and similar small package, good functional drop-in alternative.
  • 74LVC1G139GM,115 --: Same LVC 1G139 decoder function from an alternate supplier, different series prefix and package code for easy distinction.
  • 74LVC1G139GW --: Same dual 2-to-4 line decoder function in a different package and series, pin-compatible logic family with similar voltage range.
  • 74LVC1G139GM --: Same decoder function in a smaller leadless package, good alternative when board space is limited.
