Notes
* Indicates JEDEC registered data.
1. The current transfer ratio(I
C
/I
F
) is the ratio of the detector collector current to the LED input current with V
CE
@ 10 V.
2. Pulse test: pulse width = 300µs, duty cycle 2.0% .
3. For test circuit setup and waveforms, refer to figure 7..
4. I
F
adjusted to I
C
= 2.0 mA and I
C
= 0.7 mA rms.
5. The frequency at which I
C
is 3dB down from the 1 KHz value.
6. For this test, LED pins 1 and 2 are common, and phototransistor pins 4,5 and 6 are common.
