The ATF1502AS includes an optional pin-controlled power-down feature. When this mode is
enabled, the PD pin acts as the power-down pin. When the PD 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 registered 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
the power-down pin may not use the PD pin logic array input. However, all other PD pin mac-
rocell resources may still be used, including the buried feedback and foldback product term
array inputs.

shoot to -2.0V for pulses of less than 20 ns.
Maximum output pin voltage is V
which may overshoot to 7.0V for pulses of less
than 20 ns.

Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.
