69 / 386 page  3-17 DC and Switching Characteristics Lattice Semiconductor LatticeECP2/M Family Data Sheet Typical Building Block Function Performance 1 Pin-to-Pin Performance (LVCMOS25 12mA Drive) Function -7 Timing Units Basic Functions 16-bit Decoder 3.8 ns 32-bit Decoder 4.5 ns 64-bit Decoder 5.0 ns 4:1 MUX 3.2 ns 8:1 MUX 3.4 ns 16:1 MUX 3.5 ns 32:1 MUX 4.0 ns 1. These timing numbers were generated using the ispLEVER design tool. Exact performance may vary with device and tool version. The tool uses internal parameters that have been characterized but are not tested on every device.
