With a CMOS gate to drive the optocoupler, the circuit
shown in Figure 19 can be used. The diode in parallel to
the current limiting resistor speeds the turn-off of the
optocoupler LED. Any HC or HCT series CMOS gate can
be used in this circuit.
For high common-mode rejection applications, the drive
circuit shown in Figure 20 is recommended. In this circuit,
only an open-collector TTL, or an open drain CMOS gate
can be used. This circuit drives the optocoupler LED with
a 220 ohm current-limiting resistor to ensure that an I
of 7 mA is applied under worst case conditions and thus
guarantee the 10,000 V/μs optocoupler common mode
rejection rating. The designer can obtain even higher
common-mode rejection performance than 10,000 V/μs
by driving the LED harder than 7 mA.
Phase Relationship to Input
The output of the optocoupler is inverted when
compared to the input. The input is defined to be logic
HIGH when the LED is ON. If there is a design that requires
the optocoupler to behave as a non-inverting gate, then

the series input drive circuit shown in Figure 19 can be
used. This input drive circuit has an inverting function,
and since the optocoupler also behaves as an inverter,
the total circuit is non-inverting. The shunt drive circuits
shown in Figures 18 and 20 will cause the optocoupler to
function as an inverter.
Current and Voltage Limitations
The absolute maximum voltage allowable at the output
supply voltage pin and the output voltage pin of the opt-
ocoupler is 7 volts. However, the recommended maximum
voltage at these two pins is 5.5 volts. The output sinking
current should not exceed 13 mA in order to make the
Low Level Output Voltage be less than 0.6 volt. If the
output voltage is not a consideration, then the absolute
maximum current allowed through the ACSL-6xx0 is 50
mA. If the output requires switching either higher currents
or voltages, output buffer stages as shown in Figures 21
and 22 are suggested.
