Device identity and parametric baseline
The SN74LV138ANS is a 1-of-8 decoder/demultiplexer from the 74LV low-voltage CMOS logic family, routing one active-low enable to one of eight active-low outputs based on a three-bit address. Output drive is rated 12 mA sink and 12 mA source, sufficient for driving standard CMOS inputs or low-power LEDs without a buffer stage.
Housed in a 16-SOIC (0.209-inch body width, 5.30 mm) with supplier package code 16-SO, the part mounts on standard SOIC footprints and is compatible with reflow soldering profiles typical for lead-free assemblies.
Lifecycle and compliance posture
ROHS3 compliant, with no exemptions that would restrict its use in EU-market equipment or RoHS-driven BOMs.
