The PC7410 provides several I/O voltages to support both compatibility with existing
systems and migration to future systems. The PC7410 “core” voltage must always be
provided at nominal voltage (see Table 4 for actual recommended core voltage). Volt-
age to the L2 I/Os and processor interface I/Os are provided through separate sets of
supply pins and may be provided at the voltages shown in Table 3. The input voltage
threshold for each bus is selected by sampling the state of the voltage select pins at the
negation of the signal HRESET. The output voltage will swing from GND to the maxi-
mum voltage applied to the O

Notes:
1. Caution: The input threshold selection must agree with the OV

supplied.
2. To select the 2.5V threshold option, L2VSEL/BVSEL should be tied to HRESET so
that the two signals change state together. This is the preferred method for selecting
this mode operation.
3. To overcome the internal pull-up resistance, a pull-down resistance less than 250
should be used.

7. NSpec does not support the default OV

tie either low or HRESET.
