Frequently Asked Questions
Is the CD74HC125QPWRCT automotive qualified?
Yes, the CD74HC125QPWRCT carries the Q suffix indicating AEC-Q100 automotive qualification, making it suitable for use in automotive electronic systems operating under harsh temperature and reliability requirements in applications such as ECUs and body control modules.
How many buffer channels does the CD74HC125QPWRCT have?
The CD74HC125QPWRCT provides four independent non-inverting buffer channels, each with its own active-low output enable pin, allowing individual control of each buffer's three-state output for flexible bus management and signal routing.
What is the supply voltage range of the CD74HC125QPWRCT?
The CD74HC125QPWRCT operates over a supply voltage range of 2V to 6V, providing compatibility with 2.5V, 3.3V, and 5V digital logic systems and enabling use in mixed-voltage designs common in modern automotive and industrial electronics.
What package is the CD74HC125QPWRCT available in?
The CD74HC125QPWRCT is available in a TSSOP (Thin Shrink Small Outline Package) format, offering a compact surface-mount footprint well-suited for space-constrained automotive PCB designs while maintaining easy soldering and inspection.
What does the three-state output feature provide in the CD74HC125QPWRCT?
The three-state outputs allow the CD74HC125QPWRCT buffer outputs to be placed in a high-impedance state when the active-low enable pin is deasserted, preventing bus contention when multiple drivers share a common data or address bus in digital systems.
