Minimum DC input is –0.5 V. During transitions, the inputs may undershoot to –0.5 V or overshoot to 4.1 V for input
currents less than 100 mA and periods shorter than 20 ns.

All pins, including dedicated inputs, clock, I/O, and JTAG pins, may be driven before V
powered.
Typical values are for T
These values are specified under the Mercury Device Recommended Operating Conditions shown in

Input pins are grounded. In the test design, internal logic does not toggle. The test design does not use PLL or HSDI
circuitry. All ESBs are in power-down mode.
Pin pull-up resistance values will lower if an external source drives the pin higher than V

accuracy is within 5%.

The high-performance multi-level FastTrack Interconnect routing
resources ensure predictable performance, accurate simulation, and
accurate timing analysis. The predictable performance of Mercury devices
offer an advantage over FPGAs, which use a segmented connection
scheme and therefore have unpredictable performance.
