ACPL-M61U-000E
Wide Operating Temperature 10MBd Digital
Optocoupler R2Coupler™ Isolation
Description
The Broadcom® ACPL-M61U is a small outline wide
operating temperature, high CMR, high speed, logic gate
optocoupler. It is a single channel device in a five lead
miniature footprint.
The ACPL-M61U optically coupled gates combine a AlGaAs
light emitting diode and an integrated high gain photo
detector. The output of the detector IC is an Open-collector
Schottky-clamped transistor. The internal shield provides a
guaranteed minimum common mode transient immunity

This optocoupler is suitable for use in industrial high speed
communications logic interfacing with low propagation
delays, input/output buffering and is recommended for use
in high operating temperature environment.
This unique design provides maximum AC and DC circuit
isolation while achieving TTL compatibility. The optocoupler
AC and DC operational parameters are guaranteed from
–40°C to 125°C.

NOTE:
1. Bypassing of the power supply line is required with a 0.1 μF ceramic disc capacitor adjacent to each
optocoupler. The total lead length between both ends of the capacitor and the isolator pins should not exceed
10 mm.
2. Peaking circuits may produce transient input currents up to 40 mA, 50 ns maximum pulse width, provided
average current does not exceed 20 mA.
3. Device considered a two terminal device: pins 1 and 3 shorted together and pins 4, 5 and 6 shorted together.
4. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage
≥ 4500VRMS for 1 second (leakage detection current limit, II-O ≤ 5 μA).
5. The tPLH propagation delay is measured from 3.25 mA point on the falling edge of the input pulse to the 1.5V
point on the rising edge of the output pulse.
6. The tPHL propagation delay is measured from 3.25 mA point on the rising edge of the input pulse to the 1.5V
point on the falling edge of the output pulse.
7. CMH is the maximum tolerable rate of rise of the common mode voltage to assure that the output will remain
in a high logic state (for example, VOUT > 2.0V).
8. CML is the maximum tolerable rate of fall of the common mode voltage to assure that the output will remain in
a low logic state (for example, VOUT < 0.8V).
9. For sinusoidal voltages, (|dVCM|/dt)max = πfCMVCM(p-p).
10. See application section Propagation Delay, Pulse-Width Distortion, and Propagation Delay Skew for more
information.
11. tPSK is equal to the worst case difference in tPHL and/or tPLH that will be seen between units at any given
temperature within the worst case operating condition range.
12. Input current derates linearly above 85°C free-air temperature at a rate of 0.25 mA/°C.
13. Input power derates linearly above 85°C free-air temperature at a rate of 0.375 mW/°C.
14. Output power derates linearly above 85°C free-air temperature at a rate of 0.475 mW/°C.

ACPL-M61U-000E Data Sheet
Propagation Delay, Pulse-Width Distortion, and Propagation Delay Skew
Propagation delay is a figure of merit which describes how
quickly a logic signal propagates through a system. The
propagation delay from low to high (tPLH) is the amount of
time required for an input signal to propagate to the output,
causing the output to change from low to high. Similarly, the
propagation delay from high to low (tPHL) is the amount of
time required for the input signal to propagate to the output,
causing the output to change from high to low (see
Figure 6).
Pulse-width distortion (PWD) results when tPLH and tPHL
differ in value. PWD is defined as the difference between
tPLH and tPHL and often determines the maximum data rate
capability of a transmission system. PWD can be expressed
in percent by dividing the PWD (in ns) by the minimum pulse
width (in ns) being transmitted. Typically, PWD on the order
of 20% to 30% of the minimum pulse width is tolerable; the
exact figure depends on the particular application (RS232,
RS422, T-1, and so forth).
Propagation delay skew, tPSK, is an important parameter to
consider in parallel data applications where synchronization
of signals on parallel data lines is a concern. If the parallel
data is being sent through a group of optocouplers,
differences in propagation delays will cause the data to
arrive at the outputs of the optocouplers at different times. If
this difference in propagation delays is large enough, it will
determine the maximum rate at which parallel data can be
sent through the optocouplers.
Propagation delay skew is defined as the difference
between the minimum and maximum propagation delays,
either tPLH or tPHL, for any given group of optocouplers
which are operating under the same conditions (i.e., the
same drive current, supply voltage, output load, and
operating temperature). As illustrated in Figure 14, if the
inputs of a group of optocouplers are switched either ON or
OFF at the same time, tPSK is the difference between the
shortest propagation delay, either tPLH or tPHL, and the
longest propagation delay, either tPLH or tPHL.
outputs of the optocouplers. To obtain the maximum data
transmission rate, both edges of the clock signal are being
used to clock the data; if only one edge were used, the clock
signal would need to be twice as fast.
Propagation delay skew represents the uncertainty of where
an edge might be after being sent through an optocoupler.
Figure 15 shows that there will be uncertainty in both the
data and the clock lines. It is important that these two areas
of uncertainty not overlap, otherwise the clock signal might
arrive before all of the data outputs have settled, or some of
the data outputs may start to change before the clock signal
has arrived. From these considerations, the absolute
minimum pulse width that can be sent through optocouplers
in a parallel application is twice tPSK. A cautious design
should use a slightly longer pulse width to ensure that any
additional uncertainty in the rest of the circuit does not
cause a problem.
The tPSK-specified optocouplers offer the advantages of
guaranteed specifications for propagation delays, pulsewidth distortion and propagation delay skew over the
recommended temperature, and input current, and power
supply ranges.

As mentioned earlier, tPSK can determine the maximum
parallel data transmission rate. Figure 15 shows the timing
diagram of a typical parallel data application with both the
clock and the data lines being sent through optocouplers.
