VOL
SYMBOL
1. One output at a time for a maximum duration of one second. VOUT = 0.5V was selected to avoid test
problems by tester ground degradation. Characterized but not 100% tested.
2. Measured using eight 16-bit counters.
3. Typical values are at VCC = 2.5V and TA = 25°C.
4. Maximum ICC varies widely with specific device configuration and operating frequency. Refer to Power Consumption
section of this data sheet and Thermal Management section of the Lattice Semiconductor Data Book or CD-ROM to
estimate maximum ICC.
5. With no pull-up resistors.
