7.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted) (1)
MIN MAX UNIT(2)
VBIAS BIAS voltage range –0.5 6.5 V
VIN Input voltage range –0.5 VBIAS + 0.5 V
VOUT Output voltage range –0.5 VBIAS + 0.5 V
VON Input voltage range –0.5 6.5 V
IMAX Maximum Continuous Switch Current 200 mA
IPLS Maximum Pulsed Switch Current, pulse <300us, 2% duty cycle 400 mA
TA Operating free-air temperature range(3) –40 85 °C
TJ Maximum junction temperature 125 °C
TSTG Storage temperature –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground terminal.
(3) Inapplications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may have to be derated. Maximum ambient temperature [TA(max)] is dependent on the maximum operating junction temperature [TJ(max)], the maximum power dissipation of the device in the application [PD(max)], and the junction-to-ambient thermal resistance of the part/package in the application (θJA), as given by the following equation: TA(max) = TJ(max) – (JA × PD(max))

7.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) 2000 V
Charged-device model (CDM), per JEDEC specification JESD22-C101(2) 1000
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions.

7.3 Recommended Operating Conditions

VIL, ON Low-level input voltage, ON VBIAS = 5 V 0 0.8 V
CIN Input Capacitor 1 µF
