The MC14536B programmable timer is a 24-stage binary ripple counter with 16 stages selectable by a binary code. Provisions for an on-chip RC oscillator or an external clock are provided. An on-chip monostable circuit incorporating a pulse-type output has been included. By selecting the appropriate counter stage in conjunction with the appropriate input clock frequency, a variety of timing can be achieved.
The MC14536B is a programmable timer IC featuring a 24‑stage binary ripple counter. Up to 24 stages are selectable via a four‑bit code, with provisions for an on‑chip RC oscillator or an external clock. The device includes an on‑chip monostable circuit and can drive low‑power TTL or Schottky loads.
The datasheet provides electrical and switching characteristics, pin descriptions, truth tables, package dimensions, and ordering information for PDIP‑16 and SOIC‑16 variants. It also includes typical RC oscillator and monostable performance graphs.
