Data Sheet
ACML-7400, ACML-7410, and ACML-7420
3.3V/5V 100-MBd High-Speed CMOS Digital
Isolator
Description
The Broadcom® ACML-7400, ACML-7410, and ACML7420 are multi-channel, high-speed CMOS digital isolators.
Using magnetic coupling through a thick insulation barrier,
the isolators enable high speed transmissions without
compromise in isolation performance. These isolators
consume low power even at high data rates, yet provide
excellent transient immunity performance in compact
surface-mount packages. The devices are qualified to a
maximum propagation delay of 36 ns and a maximum pulse
width distortion of 3 ns. They are capable of running at a 100
MBaud data rate.
Features
UL Recognised
ACML-7400, ACML-7410 ,and ACML-7420 are available in
16-pin SOIC wide-body packages. They operate at dual
3.3V/5V supply voltages. The DC and timing specifications
are specified over the temperature range of –40°C to
+105°C. ACML-7400, ACML-7410, and ACML-7420 are
built using CMOS input buff ers and CMOS output drivers to
eliminate the need for both input limiters and output pull-up
resistors. Refresh circuitry is built in to ensure DCcorrectness.

a. tPHL propagation delay is measured from the 50% level on the falling edge of the VIN signal to the 50% level of the falling edge of the VOUT
signal. tPLH propagation delay is measured from the 50% level on the rising edge of the VIN signal to the 50% level of the rising edge of the
VOUT signal.
b. PWD is defined as tPHL – tPLH.
c. tCSK is equal to the magnitude of the worst case diff erence in tPHL and/or tPLH that will be seen between channels of the same unit at any
given temperature and supply voltages within the recommended operating conditions.
d. tPSK is equal to the magnitude of the worst case diff erence in tPHL and/or tPLH that will be seen between units at any given temperature and
supply voltages within the recommended operating conditions.
e. tENABLE is the duration when VOE is set to High state and output is restored per input signal (VO = VIN).
f. tDISABLE is the duration when VOE is set to Low and VO is switched to high impedance state.
g. CMH is the maximum common mode voltage slew rate that can be sustained while maintaining VOUT > 0.8 VDD2. CML is the maximum
common mode input voltage that can be sustained while maintaining VOUT < 0.8V. The common mode voltage slew rates apply to both rising
and falling common mode voltage edges.

3.3V/5V 100-MBd High-Speed CMOS Digital Isolator
Supply Current Consumption
Bypassing and PC Board Layout
It should be noted that the output supply current is specified
under no load conditions. Additional supply current
consumption from board or components loading can be
computed based on:
The ACML-7400 series digital isolators are extremely easy
to use. No external interface circuitry is required because
ACML-7400 series use high speed CMOS IC technology
allowing CMOS logic to be connected directly to the inputs
and outputs.
IDD = CVF
Where IDD is the additional supply current consumption per
output channel, C is the load capacitance, V is the supply
voltage and F is the frequency of the signal
As shown in Figure 13, the only external components
required for proper operation are two bypass capacitors for
decoupling the power supply. Capacitor values should
typically be 0.1 µF. For each capacitor, the total lead length
between both ends of the capacitor and the power supply
pins should be as short as possible.
