The MC74HC163N is a high-performance integrated circuit (IC) manufactured by Texas Instruments, a global semiconductor industry leader known for its high-quality products.

• Series: MC74HC series
• Type: high-speed CMOS 4-bit binary counter
• Function: synchronous presettable binary counter
• Package: 16-pin DIP (Dual Inline Package)
• Pins: 4-bit binary inputs, binary outputs, a carry output, a clock input, and reset and preset enables
• Direction: can count both upwards and downwards
• Operation: synchronous operation
• Timing: the state of the counter advances on the rising edge of the clock signal
• Technology: silicon-gate CMOS technology
• Advantages: lower power consumption, wider operating voltage range, and better noise immunity
• Feature: presettable capability
• Function: allows the user to set the counter to any desired state @ any time, independent of the clock signal
