Description
7492 – 4-Bit Divide-by-12 Binary Counter (TTL)
📄 **Description:
The 7492** is a 4-bit asynchronous binary counter designed using TTL logic. Internally, it is configured as a divide-by-12 counter, made by combining a divide-by-2 and a divide-by-6 stage. It consists of four master-slave flip-flops connected in a specific pattern to count in a preset sequence.
The counter advances on the negative edge of the clock and is widely used in frequency division, event counting, and digital time base generation. It also includes asynchronous clear (reset) functionality to reset all outputs to zero instantly.
