The -40°C to 85°C industrial temperature range covers most factory-floor and outdoor enclosure environments, though not extended automotive under-hood duty. The single-supply architecture simplifies board layout — no dual rails or sequencing required. Outputs source or sink 8mA, sufficient to drive a standard CMOS load or a low-power LED indicator through a series resistor. ## Package and footprint fit Housed in a 16-SOIC (0.154\" body width, 3.90mm), the SN74AHC138D uses the same land pattern as the industry-standard SOIC-16. The 1.27mm pin pitch is routable on a two-layer board without micro-vias, and the package is compatible with reflow profiles typical for lead-free assemblies. ## Sourcing and compliance Texas Instruments lists this device as Active with ROHS3 compliance.","metaTitle":"SN74AHC138D Decoder/Demux, 1x3:8, 2-5.5V, 16-SOIC","metaDescription":"SN74AHC138D 1-of-8 decoder/demultiplexer, 2V-5.5V supply, 8mA output drive, -40°C to 85°C, 16-SOIC.
