IL600A Series Isolators
Non-inverting and Inverting Configurations
IL600-Series Isolators can be configured in non-
inverting and inverting configurations (see Figure
3). In a typical non-inverting circuit, the In ?
terminal is connected via a 1 k ? input resistor to
the supply rail, and the input is connected to the In+
terminal. The supply voltage is +5 V and the input
signal is a 5 V CMOS signal. When a logic high
(+5 V) is applied to the input, the current through

the coil is zero. When the input is a logic low (0 V),
at least 5 mA flows through the coil from the In ?
side to the In+ side.
The inverting configuration is similar to standard

logic. In the inverting configuration, the signal into
the coil is differential with respect to ground. The
designer must ensure that the difference between
the logic low voltage and the coil ground is such

that the residual coil current is less than 0.5 mA.
The IL612 and IL614 devices have some inputs
that do not offer inverting operation. The IL612
coil In ? input is hardwired internally to the device
power supply; therefore it is important to ensure the
isolator power supply is at the same voltage as the

power supply to the source of the input logic signal.
The IL614 has a common coil In ? for two inputs.
This pin should be connected to the power supply
for the logic driving channels 2 and 3, and the
channels run should be run in non-inverting mode.
Both single ended and differential inputs can be
handled without reverse bias protection.

Boost Capacitor
The boost capacitor in parallel with the current-limiting resistor boosts the instantaneous coil current at the signal transition. This
ensures switching and reduces propagation delay and reduces pulse-width distortion.
Select the value of the boost capacitor based on the rise and fall
times of the signal driving the inputs. The instantaneous boost

capacitor current is proportional to input edge speeds ( C dVdt ). Select a
capacitor value based on the rise and fall times of the input signal to be
isolated that provides approximately 20 mA of additional “boost”
current. Figure 4 is a guide to boost capacitor selection. For high-speed
logic signals (t r ,t f < 10 ns), a 16 pF capacitor is recommended. The
capacitor value is generally not critical; if in doubt, choose a higher
value.
