Output AC Test Loads
The ATF1508ASV(L) includes two pins for optional pin-controlled power-down feature.
When this mode is enabled, the PD pin acts as the power-down pin. When the PD1 and
PD2 pin is high, the device supply current is reduced to less than 5 mA. During power-
down, all output data and internal logic states are latched and held. Therefore, all regis-
tered and combinatorial output data remain valid. Any outputs that were in a high-Z state
at the onset will remain at high-Z. During power-down, all input signals except the
power-down pin are blocked. Input and I/O hold latches remain active to ensure that
pins do not float to indeterminate levels, further reducing system power. The power-
down pin feature is enabled in the logic design file. Designs using either power-down pin
may not use the PD pin logic array input. However, buried logic resources in this macro-
cell may still be used.
