Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
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
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at

Description
These optocouplers consist of an AlGaAS LED, optically
coupled to a very high speed integrated photo-detector
logic gate. Devices include a strobable output. This
output features an open collector, thereby permitting
wired OR outputs. The coupled parameters are
guaranteed over the temperature range of -40°C to
+85°C. A maximum input signal of 5 mA will provide a
minimum output sink current of 13 mA (fan out of 8). An
internal noise shield provides superior common mode
rejection of typically 50 kV/µs at 1,000V common mode.
