NOTES:
6. IRQ1/FOUT inactive.
7. Typical values are for T = +25°C and 3.3V supply voltage.
8. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
9. These are I2C specific parameters and are not production tested; however, they are used to set conditions for testing devices to validate
specification.
10. Parts will work with SDA pull-up voltage above the VPULLUP limit but the tAA and tFin the I2C parameters are not guaranteed.
11. Specified at +25°C.
Serial Interface Specifications Over the recommended operating conditions unless otherwise specified. Boldface limits apply over
the operating temperature range, -40°C to +85°C. (Continued)
