Recommended Operating Conditions
This device contains circuitry to protect the inputs against damage due to high static voltages
or electric fields; however, it is advised that normal precautions be taken to avoid application
of any voltage higher than maximum rated voltages to this high impedance circuit. Unused
inputs must always be tied to an appropriate logic voltage level.
Power Supply Sequencing
The Tsi148 uses the 1.8V supply to power its core logic and the 3.3V supply to power its I/O
buffers. If the 3.3V is supplied before the 1.8V, the Tsi148 I/O buffers are in an undefined
state, and possibly driving, until the core 1.8V is applied. It is recommended to supply the
1.8V before, or concurrently, with the 3.3V supply.
If the board design requires the 3.3V be supplied before the 1.8V supply, contact IDT's
Applications Engineering team.
