- **Clock Input:** Synchronous (Positive Edge-Triggered)
- **Reset Function:** Synchronous Clear (Active LOW)
- **Load Function:** Parallel Load Capability (Active LOW)
- **Output Type:** Standard TTL (Totem Pole)
### **Descriptions:**
- The SN54163J is a synchronous 4-bit binary counter with a fully synchronous operation, meaning all state changes occur on the rising edge of the clock signal.
- It features a synchronous clear (reset) function, ensuring that the counter resets only on the clock edge when the clear input is active.
- The counter can be preset to any value using the parallel load input.
- It includes carry look-ahead circuitry for high-speed counting applications.
- Designed for military and industrial applications due to its wide operating temperature range.
### **Features:**
- **Synchronous Counting:** All flip-flops are clocked simultaneously.
- **Parallel Load Capability:** Allows loading a preset value into the counter.
- **Synchronous Clear:** Resets the counter synchronously with the clock.
- **Carry Output:** Provides ripple carry for cascading multiple counters.
- **High-Speed Operation:** Optimized for fast counting applications.
- **Wide Operating Temperature Range:** Suitable for harsh environments.
