8-SOIC footprint and supply range
The SA555D is a 555-type timer/oscillator from Texas Instruments in an 8-SOIC package (0.154" wide, 3.90 mm body). The surface-mount footprint matches the standard SOIC-8 land pattern — the 1.27 mm pitch is board-friendly for two-layer designs without via-in-pad. The 10 mA supply current at 100 kHz maximum oscillation is the total device draw — no external timing components are included in that figure.
Industrial temperature grade and active lifecycle
The 100 kHz maximum frequency is the oscillator ceiling — the actual output frequency is set by external R and C components, and the timing accuracy depends on their tolerance and temperature coefficient.
