Frequently Asked Questions
What is the supply voltage range for the CD74HC190E?
The CD74HC190E 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 allows flexible integration into a variety of embedded and industrial designs.
What package does the CD74HC190E come in?
The CD74HC190E is available in a 16-Pin PDIP (Dual In-Line Package), which is well suited for through-hole PCB assembly and prototyping on breadboards. The PDIP package simplifies manual soldering and rework.
Can the CD74HC190E be cascaded for larger count ranges?
Yes, the CD74HC190E features a Ripple Carry Output (RCO) pin specifically designed for cascading multiple counter ICs. By connecting the RCO of one stage to the enable input of the next, you can build multi-decade counters capable of counting beyond 9.
What logic family does the CD74HC190E belong to, and what are the benefits?
The CD74HC190E belongs to the HC/UH (High-Speed CMOS) family. This family offers high noise immunity, low quiescent current consumption, and fast switching speeds, making it suitable for battery-powered and noise-sensitive industrial applications.
Is the CD74HC190E RoHS compliant?
Yes, the CD74HC190E carries a Pb-free (lead-free) code indicating RoHS compliance. The JESD-609 code e4 confirms the component meets international environmental standards for hazardous substance restrictions.
