The DM74163N is a synchronous 4-bit binary counter manufactured by National Semiconductor, now part of Texas Instruments (TI). This counter features a synchronous clear input and a carry output for cascading multiple counters. It is part of the 7400 series of TTL logic chips. As an END-OF-LIFE component, the DM74163N is no longer actively manufactured but may still be available through distributors or found in legacy systems.

Additional Details
The DM74163N typically comes in a 16-pin DIP (Dual In-line Package). Key specifications include the maximum clock frequency, supply voltage range, and propagation delays. The synchronous clear input allows for resetting the counter to zero on the next clock pulse. The carry output indicates when the counter has reached its maximum count, allowing for cascading with other DM74163N devices to create counters of arbitrary length. Consult the device datasheet for complete electrical characteristics and application information. The 'N' suffix typically denotes a plastic DIP package.
