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 ACML-
7420 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.
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 DC-
correctness.
Features
Dual supply voltage compatible – 3.3V and 5V
Wide operating temperature range (-40° C to +105° C)

Lower power consumption – 15 mA per channel typical
Low propagation delay: 36 ns max.
Low propagation delay skew
– Channel-to-channel: 4 ns max.
– Part-to-part: 8 ns max.
Low pulse width distortion: 3 ns max.

These isolators are suitable for
safe electrical isolation
only within the safety limit data. Maintenance of the safety
