Frequently Asked Questions
What is the counting mode of the SN74HC163DRE4?
The SN74HC163DRE4 is a 4-bit synchronous binary counter that counts in the UP direction. All count transitions are synchronized to the clock edge, eliminating output glitches and making it reliable for high-speed digital applications requiring precise timing.
How can the SN74HC163DRE4 be cascaded for wider counter widths?
The SN74HC163DRE4 includes a Ripple Carry Output (RCO) pin specifically designed for cascading multiple counters. By connecting the RCO of one device to the enable input of the next, you can build 8-bit, 12-bit, or wider counters without additional glue logic.
Does the SN74HC163DRE4 support synchronous preset/load?
Yes, the SN74HC163DRE4 has a synchronous load/preset input that allows loading a specific 4-bit value on the next clock edge. This eliminates asynchronous glitches and is essential for programmable counters or sequence generators where start values must be reliably set.
What package and lead finish does the SN74HC163DRE4 use?
The SN74HC163DRE4 comes in a 16-Pin SOIC (Small Outline Integrated Circuit) surface-mount package. The 'G4' suffix indicates a RoHS-compliant e4 lead-free finish, making it suitable for use in products that require environmental compliance under EU RoHS and similar regulations.
What is the estimated product lifespan for the SN74HC163DRE4?
Texas Instruments lists the SN74HC163DRE4 with a YTEOL (Years to End of Life) of 15 years, providing strong confidence for long-term production design-ins and reducing the risk of unexpected part obsolescence in industrial or commercial applications.
