Notes:

a. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum and over - 40 °C to 85 °C.

b. Typical values are specified for 25 °C operation, and are for design reference only.

c. Not 100 % tested in production. This information is provided for reference only.

d. IN A or IN B switching at 250 kHz, RDEL = 25 k to ground.

e. IN A = step 5 to 0 V and IN B = 5 V or vice versa, RDEL = 25 k to ground, error amplifier configured as voltage follower with EA+ connected

to VREF.
