Multi-channel, high-speed digital isolator
with robust HV insulation from Avago
Avago Technologies has announced the new ACML-74x0 family
of digital isolator devices based on patented magnetic coupler
technology.
The ACML-74x0 family's robust insulation is UL recognized
at 5.6 kVRMS for 1 minute. During data transmission, the
devices send low current pulses across the isolation barrier,
maintaining low electromagnetic interference (EMI) emissions
even at high data rates. The isolators integrate a quad-channel
structure, and offer uni- or bi-directional configurations,
to provide PCB savings.
Additional ACML-74x0 Product Features:
Low power consumption of 13 mA per channel typical at 100
MBd data rate
Wide operating temperature range from -40° C to 105°
C
Qualified to low maximum propagation delay of 32 ns and
low maximum pulse width distortion of 2 ns
Low propagation delay skews of 4 ns maximum for channel-to-channel
and 5 ns maximum for part-to-part
Dual supply voltage compatible for 3.3V and 5V
High common mode transient immunity of 25 kV/µs min
Safety and regulatory approvals from UL, CSA and IEC 60950-1/61010-1/60601-1
The ACML-7400 device offers an all-in-one channel configuration,
the ACML-7410 offers a bi-directional 3/1 channel configuration,
and the ACML-7420 offers a bi-directional 2/2 channel configuration.
