1. One output at a time for a maximum duration of one second. V
OUT
= 0.5V was selected to avoid test problems
by tester ground degradation. Characterized but not 100% tested.
2. Measured using four 16-bit counters.

= 5V and T

= 25°C.
4. Maximum I

varies widely with specific device configuration and operating frequency. Refer to the Power Consumption
section of this data sheet and Thermal Management section of the Lattice Semiconductor Data Book or CD-ROM to
