9 Power Supply Recommendations
The TLK10031 allows either the core or I/O power supply to be powered up for an indefinite period of time
while the other supply is not powered up, if all of the following conditions are met:
1. All maximum ratings and recommending operating conditions are followed
2. Bus contention while 1.5/1.8V power is applied (>0V) must be limited to 100 hours over the projected
lifetime of the device.
3. Junction temperature is less than 105°C during device operation. Note: Voltage stress up to the
absolute maximum voltage values for up to 100 hours of lifetime operation at a TJ of 105°C or lower
will minimally impact reliability.
The TLK10031 LVCMOS I/O are not failsafe (i.e. cannot be driven with the I/O power disabled). TLK10031
inputs should not be driven high until their associated power supply is active.
