### **Descriptions:**
The SN54LS160J is a synchronous, presettable decade counter with a fully independent clock circuit. It features synchronous counting and parallel load capability, making it suitable for high-speed counting applications. The counter advances on the rising edge of the clock signal when enabled. It includes a master reset (clear) function that synchronously resets all flip-flops.
### **Features:**
- **Synchronous Operation:** Clocked counting with parallel load capability.
- **Decade Counting:** BCD (Binary-Coded Decimal) output (0000 to 1001).
- **Parallel Load Inputs:** Allows presetting the counter to any value.
- **Synchronous Clear:** Master reset function clears outputs on the clock edge.
- **Carry Output:** Provides ripple carry for cascading multiple counters.
- **Low Power Consumption:** LS technology ensures efficient power usage.
- **Wide Operating Temperature Range:** Suitable for military and industrial applications.
