Overview
The Texas Instruments SN74HC163DR is a 4-bit synchronous binary counter integrated circuit (IC). It is designed for high-speed counting applications and features synchronous operation, making it ideal for various digital logic and control circuits. The device uses a clock input to count through 16 states and includes synchronous parallel load inputs and a carry-out output for cascading multiple ICs. It operates with a wide supply voltage range of 2 V to 6 V and has a typical propagation delay of 14 ns to 16 ns, depending on the voltage.
