5. Binary Counting: Each counter can independently count from 0 to 15 in binary form.
6. Cascade Capability: The IC can be connected in cascade to form larger counting sequences.
7. TTL Compatibility: Ensures compatibility with TTL logic levels.
8. Operating Temperature Range: Typically from -40°C to 85°C, suitable for industrial and commercial applications.
9. Standard Pin Configuration: Available in a DIP-14 package for easy integration into breadboards and PCBs.
These features make the SN74HC393N suitable for a variety of digital applications requiring counting or divide-by-N functionality.
Pinout
1. GND (Pin 7): Ground.
2. VCC (Pin 14): Positive voltage supply.
3. Q0A, Q1A, Q2A, Q3A (Pins 1, 2, 3, 4): Output pins for the first 4-bit counter.
4. Q0B, Q1B, Q2B, Q3B (Pins 13, 12, 11, 10): Output pins for the second 4-bit counter.
5. CLOCK A (Pin 5): Clock input for the first counter.
6. CLOCK B (Pin 9): Clock input for the second counter.
7. CLEAR A (Pin 6): Asynchronous clear for the first counter.
8. CLEAR B (Pin 8): Asynchronous clear for the second counter.
The CLEAR pins are used to reset the counters to zero, independent of the clock. The counters operate on the rising edge of the clock signals.
