24 MHz toggle rate on a 3V to 18V rail
It clocks at 24 MHz on a positive edge, making it fast enough for moderate-speed control logic, debounce circuits, and frequency dividers in systems that need to run across a wide supply range. The 3V to 18V supply span is the hallmark of the 4000B family — it lets this part interface directly with 5V TTL, 12V industrial logic, or 15V analog rails without a level translator. Quiescent current sits at 4 µA typical, so it adds negligible draw in battery-backed or always-on sections. Outputs are complementary (Q and Q-bar), each sourcing or sinking 6.8 mA. Propagation delay is 90 ns at 15V with a 50 pF load, which sets the timing budget for cascaded stages.
