A separate connection for the bias of the photodiode improves the speed by several orders of magnitude over conventional phototransistor optocouplers by reducing the base-collector capacitance of the input transistor. An improved package allows superior insulation permitting a V working voltage compared to industry standard of V. Note 8 Fig. Current Transfer Ratio is de? The 4.

This output features an open collector, thereby permitting wired OR outputs. A maximum input signal of 5 mA will provide a minimum output sink current of 13mA fan out of 8. F bypass capacitor must be connected between pins 8 and 5. See note 1? Initial input current threshold value is 5. Note 10 Fig. The VCC supply to each optoisolator must be bypassed by a 0. F capacitor or larger. This can be either a ceramic or solid tantalum capacitor with good high frequency characteristic and should be connected as close as possible to the package V CC and GND pins of each device.
Each channel. Enable Input - No pull up resistor required as the device has an internal pull up resistor. CMH -The maximum tolerable rate of rise of the common mode voltage to ensure the output will remain in the high state i.
CML -The maximum tolerable rate of rise of the common mode voltage to ensure the output will remain in the low output state i. Device considered a two-terminal device: Pins 1,2,3 and 4 shorted together, and Pins 5,6,7 and 8 shorted together.
