Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values
(not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage
may occur and reliability may be affected.
DC ELECTRICAL CHARACTERISTICS Typical values are at T_A = 25°C. Minimum and Maximum values are for the full operating
temperature range: -40 to +85°C for SA575, except SSOP package is tested at +25°C only. V_CC = 5.0 V, unless otherwise stated. Both
channels are tested in the Expandor mode (see Test Circuit).

1. Operation down to V_CC = 2.0 V is possible, but performance is reduced. See curves in Figures 6 and 7.
2. Reference voltage, V_REF, is typically at 1/2 V_CC.
