ACML-7400, ACML-7410 and ACML-7420
3.3 V/5 V 100 MBd High Speed CMOS Digital Isolator
Data Sheet
CAUTION: It is advised that normal static precautions be taken in handling and assembly
of this component to prevent damage and/or degradation which may be induced by ESD.
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 quali ed 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 speci ca-
tions are speci ed over the temperature range of -40° C
to +105° C. ACML-7400, ACML-7410 and ACML-7420 are
built using CMOS input bu 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.
