555 architecture for timer and oscillator blocks
The SA555DR is a single 555-type timer/oscillator from Texas Instruments, a classic bipolar architecture rated for a maximum oscillation frequency of 100 kHz. Its supply voltage spans 4.5 V to 16 V, covering the 5 V logic rail and 12 V industrial bus, with a typical supply current of 10 mA at the nominal rail.
Surface-mount footprint in 8-SOIC
Housed in the industry-standard 8-SOIC package (0.154" width, 3.90 mm body), the SA555DR mates with the JEDEC SOIC-8 land pattern — a drop-in for existing 555 timer layouts migrating from through-hole DIP to surface mount. The supplier device package is 8-SOIC; the same footprint serves the NE555 and LM555 variants, simplifying BOM consolidation when a single board uses multiple 555 timer sources.
Active lifecycle and compliance documentation
Fully ROHS3 compliant, the part ships on Tape & Reel or Cut Tape in the 8-SOIC form factor.
