Frequently Asked Questions
What is the recommended operating voltage range for this buffer/line driver?
The device operates at low voltages, specifically from 1.2V to 3.6V.
Does the 74VCX32244 have high-speed features or advanced technology?
Yes, it includes an advanced CMOS fabric and Supports 'live insertion and withdrawal' technology for high speed while maintaining low power dissipation.
How is full 32-bit operation achieved?
Full 32-bit operation can be achieved by shorting separate 3-STATE control inputs together in a nibble (4-bit) block, allowing the device to be fully controlled.
Are there specific requirements for the Output Enable (OE) input during power changes?
To ensure high-impedance state during power up or power down, OE must be tied to V through a pull-up resistor with a minimum current value set by the driver's current-sourcing capability.
