will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore

Absolute Maximum Ratings (No derating required up to 70°C)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Notes:
6.
TPHL propagation delay is measured from the 2.5V level of the leading edge of a 5.0V input pulse (1µs rise time) to
the 1.5 V level on the leading edge of the output pulse. TPLH propagation delay is measured on the trailing edges
of the input and output pulse. (Refer to Fig. 9)
7.
Common mode transient immunity in logic high level is the maximum tolerable (positive) dVcm/dt on the leading
edge of the common mode pulse signal VCM, to assure that the output will remain in a logic high state (i.e., VO >
2.0 V). Common mode transient immunity in logic low level is the maximum tolerable (negative) dVcm/dt on the
trailing edge of the common mode pulse signal, VCM, to assure that the output will remain in a logic low state
(i.e., VO < 0.8 V). Refer to Fig. 10.
8.
In applications where dVcm/dt may exceed 50,000 V/µs (Such as static discharge), a series resistor, RCC,
should be included to protect the detector chip from destructive surge currents. The recommended value for
RCC is 240V per volt of allowable drop in VCC (between pin 8 and VCC) with a minimum value of 240Ω.
9.
Device is considered a two terminal device: Pins 1, 2, 3 and 4 are shorted together and Pins 5, 6, 7 and 8 are
shorted together.
10. The 2500 VRMS/1 min. capability is validated by a 3.0 kVRMS/1 sec. dielectric voltage withstand test.
11. AC voltage is instantaneous voltage for VTH+ & VTH-.
12. All typicals at TA = 25°C, VCC = 5V unless otherwise specified.
