Surface-mount only — no through-hole variant in this order code.
The part is a current catalog item from Maxim Integrated (now part of Analog Devices), so the datasheet, application notes, and SPICE models remain available through the manufacturer's document portal.
Yes, it is pin-compatible with the classic 555 timer footprint in the 8-SOIC package. The key difference is the CMOS output stage and 30 µA supply current versus the bipolar 555's 3-10 mA quiescent draw. For most timing, oscillator, and PWM circuits, it drops in without board changes. Verify the output drive current — the CMOS output sources and sinks less current than a bipolar 555, so heavy loads (relay coils, incandescent lamps) may need a buffer transistor.
It comes in an 8-pin SOIC package (8-SOIC, 0.154" body width, 3.90 mm width). The supplier device package is also 8-SOIC. It is surface-mount only; no DIP variant shares this order code.
