Description
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
3.3 V/5 V supply voltages. The DC and timing specifica-
tions are specified over the temperature range of -40° C
to +105° C. ACML-7400, ACML-7410 and ACML-7420 are
built using CMOS input buffers 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 – 3.3 V & 5 V
Wide operating temperature range (-40° C to +105° C)
Support high speed data rate of at least 100 MBd
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
