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 twelve 16-bit counters.
3. Typical values are at V
= 5V and T
= 25
o
C.
4. Maximum I
varies widely with specific device configuration and operating frequency. Refer to the Power Consumption sec-
tion of this datasheet and Thermal Management section of this Lattice Semiconductor Data Book or CD-ROM to estimate maximum
