The ISL71610M is a passive-input digital signal isolator
with a CMOS output. It has a similar interface but with
better performance and higher package density than
optocouplers.
Features
• Barrier Voltage Endurance
• 2.5kVRMS, for 1 minute, 600Vrms continuous
(VDE V 0884-10 certified:
file 5022321-4880-0001),
The ISL71610M is manufactured with Giant
Magnetoresistive (GMR) technology for small size, high
speed, and low power. A ceramic/polymer composite
barrier provides excellent isolation and an unlimited
barrier life. A series external resistor sets the input coil
current and a capacitor in parallel with the
current-limiting resistor provides improved dynamic
performance. This versatile component can be used to
replace a variety of optocouplers, functioning over a
wide range of data rates, edge speeds, and power supply
levels. The device output is compatible with 3.3V and 5V
supplies, allowing an interface to controllers without
additional level shifting. With the coil energized with a
minimum of ±8mA (bidirectional current) the
ISL71610M is suitable for single ended and differential
drive applications.
