• Manufacturer Part Number: ispgdx240va
• Description: In-system Programmable 3.3v Generic Digital Crosspoint
• Manufacturer: Lattice Semiconductor Corp.

1. All timings measured with one output switching, fast output slew rate setting, except
2. The delay parameters are measured with Vcc as I/O voltage reference. An additional 0.5ns delay is incurred when Vccio is
