The 16-pin DIP package (0.300\" row spacing, 7.62 mm body width) is a through-hole footprint that mates with standard 0.100\" pitch sockets or solder holes. The output can sink 24 mA and source 2.6 mA, which is enough to drive one or two standard TTL loads or a low-current LED through a series resistor. This part is at home on a benchtop, in a lab instrument, or inside a climate-controlled enclosure — not in an engine bay or an outdoor cabinet without active cooling. ## Sourcing and production status Texas Instruments continues to manufacture this 74ALS multiplexer in the 16-PDIP package. Availability is confirmed per RFQ — the part is sourced to order against your BOM quantity. The through-hole DIP package is a mature, widely stocked form factor; lead time is quoted at quote time. ## Package and footprint decisions The 16-DIP (0.300\", 7.62 mm) body requires a 0.100\" pitch through-hole layout. The supplier device package is 16-PDIP — the same mechanical outline as standard 16-pin DIPs. Board clearance below the package is not critical; the leads exit the body and bend outward. Decoupling: place a 0.1 µF ceramic capacitor between VCC (pin 16) and GND (pin 8) within 0.5 inches of the package. The 74ALS family has moderate dynamic current; a single decoupling cap per IC is sufficient for most layouts.","metaTitle":"SN74ALS151N 1 x 8:1 Multiplexer, 16-DIP, Texas Instruments","metaDescription":"SN74ALS151N 74ALS multiplexer, single 8:1, 4.5V–5.5V supply, 0°C–70°C, 16-PDIP.
