It runs on a 4.5V to 18V supply rail and draws 10 mA typical, which means it works straight off a 5V logic rail or a 12V industrial bus without an extra regulator. The -55°C to 125°C operating range is the military-grade temperature band — this is the part you reach for when a commercial 555 would drift or fail in an engine bay, a satellite thermal-vac chamber, or a downhole tool that sees 105°C ambient. ## Repair bench fit — the 8-DIP package The 8-DIP (0.300\" wide, 7.62 mm pitch) is a through-hole package that sockets into a standard DIP-8 footprint or solders directly into plated-through holes — no hot-air rework station needed, just a soldering iron and a desoldering pump. When a board comes in with a dead 555 timer, the scorch mark is usually around the output pin or the supply pin if a downstream short pulled the rail. The SE555P drops into the same socket as any industry-standard 555, so the swap takes under five minutes. ## Lifecycle and compliance It is ROHS3 Compliant, so it passes the EU RoHS directive without exemption issues — no lead in the solder-dipped leads, no restricted phthalates in the molding compound.","metaTitle":"Texas Instruments SE555P 555 Timer, 100kHz, 8-DIP, Active","metaDescription":"Texas Instruments SE555P 555 Type timer/oscillator, 100kHz, 4.5-18V supply, -55 to 125°C, 8-DIP.
