50 µs. After the RST pin is pulled high, the device will still be in reset
state for 500 ms (typical). If the RST pin is held low continuously, the
device remains in reset state.
Functional Description
IDT82V3280
The reset operation resets all registers and state machines to their
After power on, the device must be reset for normal operation.
For a complete reset, the RST pin must be asserted low for at least
