MC14536BCP [Onsemi]

The MC14536B is a programmable timer featuring 24 flip-flop stages with counts from 2^0 to 2^24. It includes a selectable 16-stage counter via a four-bit code, an 8-bypass input to skip the first eight stages, set/reset inputs, clock/oscillator inhibit inputs, on-chip RC oscillator provisions, on-chip monostable output, clock conditioning for long rise/fall times, and a test mode for fast testing. It operates from 3.0 V to 18 V supply and can drive two low-power TTL loads or one low-power Schottky TTL load.
