CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTE:
1. If an input signal is applied before the supplies are powered up, the input current must be limited to these maximum values.
2. Parts are 100% tested at +25°C. Over-temperature limits established by characterization and are not production tested.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typical values are for information purposes only. Unless otherwise noted, all tests
are at the specified temperature and are pulsed tests, therefore: T_J = T_C = T_A
Electrical Specifications V+ = +5V, GND = 0V, T_A = +25°C, R_L = 150Ω to GND, REF_G = 0.5V, REF_RB = 1.2V, CLAMP = 2.0V,
S1 = S0 = AV2 = HIZ = 0.8V, unless otherwise specified.
