PC107A [Preliminary]
2137C–HIREL–03/04
Recommended
Operating Conditions
Table 3 provides the recommended operating conditions for the PC107A.
Notes:
1. PCI pins are designed to withstand LV
DD
+ 0.5V DC when LV
DD
is connected to a 5.0V DC power supply.
2. PCI pins are designed to withstand LV
DD
+ 0.5V DC when LV
DD
is connected to a 3.3V DC power supply.
Cautions:
3. Input voltage (V
IN
) must not be greater than the supply voltage (V
DD
/AV
DD
/LAV
DD
) by more than 2.5V at all times, including
during power-on reset.
4. OV
DD
must not exceed V
DD
/AV
DD
/LAV
DD
by more than 1.8V at any time, including during power-on reset. This limit may be
exceeded for a maximum of 20 ms during power-on reset and power-down sequences.
5. V
DD
/AV
DD
/LAV
DD
must not exceed OV
DD
by more than 0.6V at any time, including during power-on reset. This limit may be
exceeded for a maximum of 20 ms during power-on reset and power-down sequences.
6. BV
DD
/GV
DD
must not exceed V
DD
/AV
DD
/LAV
DD
by more than 1.8V at any time, including during power-on reset. This limit may
be exceeded for a maximum of 20 ms during power-on reset and power-down sequences.
7. LV
DD
must not exceed V
DD
/AV
DD
/LAV
DD
by more than 5.4V at any time including during power-on reset. This limit may be
exceeded for a maximum of 20 ms during power-on reset and power-down sequences
8. LV
DD
must not exceed OV
DD
by more than 3.6V at any time, including during power-on reset. This limit may be exceeded for
a maximum of 20 ms during power-on reset and power-down sequences.
