All supplies can be varied ±5%, and operation is guaranteed. Device is tested with nominal supplies.
2
Operation is guaranteed over this reference range, but linearity is neither tested nor guaranteed.
3
All parameters are guaranteed by design.
4
All input control signals are specified with tr = tf = 5 ns (10% to 90% of 5 V) and timed from a voltage level of 1.6 V.
