MC14040B is a 12-stage binary counter constructed with MOS P-Channel and N-Channel enhancement mode devices in a single monolithic structure. It features fully static operation, diode protection on all inputs, a wide supply voltage range, and the ability to drive low-power TTL loads. It is commonly used in time delay circuits, counter controls, and frequency-driving circuits.
The MC14040B is a 12‑stage binary counter built with MOS P‑Channel and N‑Channel enhancement mode devices in a single monolithic structure. It advances the count on the negative‑going edge of the clock pulse and is suited for time‑delay circuits, counter controls and frequency‑driving applications.
The datasheet provides detailed electrical characteristics, maximum ratings, switching performance, pin assignments, truth tables, and mechanical dimensions for the PDIP‑16, SOIC‑16 and TSSOP‑16 packages. Ordering information and package dimensions are also included.
