• Manufacturer Part Number: mach435
• Description: High-density Ee Cmos Programmable Logic
• Manufacturer: Lattice Semiconductor Corp.

SWITCHING CHARACTERISTICS over COMMERCIAL operating ranges (Note 1)
(continued)
Notes:
1. See Switching Test Circuit at the end of this Data Book for test conditions.
2. Parameters measured with 32 outputs switching.
3. These parameters are not 100% tested, but are evaluated at initial characterization and at any time the design is modified
4. This parameter does not apply to flip-flops in the emulated mode since the feedback path is required for emulation.
