6N137
DESCRIPTION
The 6N137, HCPL-2601/2611 single-channel and HCPL-2630/2631
dual-channel optocouplers consist of a 850 nm AlGaAS LED, optically
coupled to a very high speed integrated photodetector logic gate
with 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 10 kV/µs. The HCPL- 2601 and
HCPL- 2631 has a minimum CMR of 5 kV/µs. The HCPL-2611 has a
minimum CMR of 10 kV/µs.

Noted:
1. The VCC supply to each optoisolator must be bypassed by a 0.1µF
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 VCC and GND pins of
each device.
2. Each channel.
3. Enable Input - No pull up resistor required as the device has an
internal pull up resistor.
4. tPLH - Propagation delay is measured from the 3.75 mA level on
the HIGH to LOW transition of the input current pulse to the 1.5 V
level on the LOW to HIGH transition of the output voltage pulse.
5. tPHL - Propagation delay is measured from the 3.75 mA level on
the LOW to HIGH transition of the input current pulse to the 1.5 V
level on the HIGH to LOW transition of the output voltage pulse.
6. tr - Rise time is measured from the 90% to the 10% levels on the
LOW to HIGH transition of the output pulse.
7. tf - Fall time is measured from the 10% to the 90% levels on the
HIGH to LOW transition of the output pulse.
8. tELH - Enable input propagation delay is measured from the 1.5 V
level on the HIGH to LOW transition of the input voltage pulse to
the 1.5 V level on the LOW to HIGH transition of the output voltage
pulse.
9. tEHL - Enable input propagation delay is measured from the 1.5 V
level on the LOW to HIGH transition of the input voltage pulse to
the 1.5 V level on the HIGH to LOW transition of the output voltage
pulse.
10. CMH - The maximum tolerable rate of rise of the common mode
voltage to ensure the output will remain in the high state (i.e.,
VOUT > 2.0 V). Measured in volts per microsecond (V/µs).
11. CML - The maximum tolerable rate of rise of the common mode
voltage to ensure the output will remain in the low output state
(i.e., VOUT < 0.8 V). Measured in volts per microsecond (V/µs).
12. Device considered a two-terminal device: Pins 1,2,3 and 4
shorted together, and Pins 5,6,7 and 8 shorted together.
