Active sourcing — no lifecycle risk
The TLC555CPW: ROHS3 compliant — the part meets current EU and global material restrictions without needing a waiver or exemption tracking.
CMOS timer — power and frequency ceiling
The LinCMOS construction draws 360 µA typical supply current, roughly two orders of magnitude below a standard bipolar 555 — a meaningful difference for battery-powered or thermally constrained designs. Maximum oscillation frequency is 2.1 MHz, which sets the upper bound for astable or monostable timing intervals; above this rate the output pulse width collapses. Supply range spans 2 V to 15 V, so the same timer can operate on a 3.3 V logic rail or a 12 V industrial bus without a separate regulator.
