The SN74LS390NG4, manufactured by Texas Instruments, is a high-performance, dual-decade counter integrated circuit that is part of the 74LS logic family. This device features two individual decade counters in a single package, making it ideal for a wide range of counting applications in digital systems.
Key Features:
- Logic Family: The SN74LS390NG4 belongs to the 74LS series, known for its low power Schottky technology which provides a balanced trade-off between speed and power consumption.
- Counter Configuration: It includes two 4-bit binary counters that can be configured to operate as separate counters or cascaded together to create an 8-bit counter.
- Counting Mode: Each counter has a divide-by-two section and a divide-by-five section, which can be combined to provide a divide-by-ten (decade) count.
- Output Capability: This device features standard TTL outputs which are capable of driving up to 10 LS-TTL loads.
- Supply Voltage: It operates on a typical 5V supply voltage, making it compatible with most TTL circuits.
- Package Type: The SN74LS390NG4 is available in a PDIP (Plastic Dual-In-Line Package) which is suitable for through-hole mounting, providing ease of integration into existing designs.
