Descriptions:
- The 74LS92N is a modulo-12 counter, combining a divide-by-2 and a divide-by-6 section.
- It has two clock inputs (CP1 and CP2) for independent control.
- Outputs include QA (divide-by-2) and QD, QC, QB (divide-by-6).
- Features asynchronous reset (MR1 and MR2) for clearing the counter.
Features:
- Asynchronous operation for flexible counting.
- Low power consumption (typical 10mW).
- TTL-compatible inputs and outputs.
- Wide operating voltage range.
- High noise immunity.
This IC is commonly used in frequency division, timing circuits, and digital counting applications.
