MAX 7000B Programmable Logic Device Data Sheet
Two inverters implement the bus-hold circuitry in a loop that weakly
drives back to the I/O pin in user mode.
Figure 10
shows a block diagram of the bus-hold circuit.

PCI
Compatibility
MAX 7000B devices are compatible with PCI applications as well as all
3.3-V electrical specifications in the
PCI Local Bus Specification
Revision 2.2
except for the clamp diode. While having multiple clamp
diodes on a signal trace may be redundant, designers can add an external
clamp diode to meet the specification.
Table 13
shows the MAX 7000B
device speed grades that meet the PCI timing specifications.
Note:
(1)
The EPM7256B and EPM7512B devices in a -5 speed grade meet all PCI timing
specifications for 66-MHz operation except the Input Setup Time to CLK—Bused
Signal parameter. However, these devices are within 1 ns of that parameter.
EPM7256B and EPM7512B devices meet all other 66-MHz PCI timing
specifications.
