Frequently Asked Questions
What is the supply voltage range for the SN74HC163N?
The SN74HC163N operates over a supply voltage range of 2V to 6V, making it compatible with both 3.3V and 5V digital logic systems. This wide range ensures flexibility in mixed-voltage designs.
What package type does the SN74HC163N come in?
The SN74HC163N is available in a 14-pin PDIP (Plastic Dual In-line Package), which is ideal for breadboard prototyping and through-hole PCB assembly in low-frequency or educational applications.
How does the synchronous clear function work on the SN74HC163N?
The SN74HC163N features a synchronous clear (CLR) input that resets all four counter outputs to zero on the next rising clock edge when asserted low. This ensures predictable, glitch-free reset behavior in synchronous digital systems.
Can the SN74HC163N be used for frequency division?
Yes, the SN74HC163N can divide an input clock frequency by any integer from 1 to 16 using its 4-bit binary count sequence. By cascading multiple devices, you can achieve higher division ratios for use in clock generation or timing circuits.
