IO33lib Low Slew Rate
Cells
The IO33lib cells comprise a series of 2.5V/3.3V input/output pads developed for low
supply voltage processes in order to interface 2.5V ASICs to 3.3V environments.
All IO33lib cells are slew rate controlled. Advantage has been taken of the 2.5V to 3.3V
level shifter (slow by construction) to reduce the slew rate without reducing speed.
