Frequently Asked Questions
What is the difference between the CD74HC163E and CD74HC161E?
The CD74HC163E has a synchronous reset function, meaning the counter clears on the next active clock edge when reset is asserted. The CD74HC161E also features a synchronous reset but with slightly different pinout behavior in some configurations. The CD74HC163E's synchronous reset avoids output glitches common with asynchronous reset devices, making it preferred in noise-sensitive applications.
Can the CD74HC163E be cascaded to create larger counters?
Yes, the CD74HC163E includes a terminal count output (TCO) that goes high when the counter reaches its maximum count of 15. By connecting the TCO of one device to the count enable input of the next, multiple CD74HC163E ICs can be cascaded to create 8-bit, 12-bit, or wider binary counters.
What is the supply voltage range of the CD74HC163E?
The CD74HC163E operates from a supply voltage of 2V to 6V, making it compatible with both 3.3V and 5V digital systems. This wide range allows it to interface directly with most modern microcontrollers and FPGAs without level-shifting circuitry.
What package is the CD74HC163E available in?
The CD74HC163E comes in a 16-pin PDIP (Plastic Dual-In-Line Package) through-hole format, which is ideal for breadboard prototyping, educational use, and legacy PCB designs. The DIP package allows easy insertion into IC sockets for testing and replacement without soldering.
