DESCRIPTION
The ISO150 is a two-channel, galvanically isolated
data coupler capable of data rates of 80MBaud, typi-
cal. Each channel can be individually programmed to
transmit data in either direction.
Data is transmitted across the isolation barrier by
coupling complementary pulses through high voltage
0.4pF capacitors. Receiver circuitry restores the pulses
to standard logic levels. Differential signal transmis-
sion rejects isolation-mode voltage transients up to
1.6kV/µs.
ISO150 avoids the problems commonly associated
with optocouplers. Optically isolated couplers require
high current pulses and allowance must be made for
LED aging. The ISO150’s Bi-CMOS circuitry oper-
ates at 25mW per channel.
ISO150 is available in a 24-pin DIP package and in a
28-lead SOIC. Both are specified for operation from
–40˚C to 85˚C.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap-
propriate precautions. Failure to observe proper handling and
installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.

ISOLATION BARRIER
Data is transmitted by coupling complementary logic pulses
to the receiver through two 0.4pF capacitors. These capaci-
tors are built into the ISO150 package with Faraday shield-
ing to guard against false triggering by external electrostatic
fields.
The integrity of the isolation barrier of the ISO150 is
verified by partial discharge testing. 2400Vrms, 60Hz, is
applied across the barrier for one second while measuring
any tiny discharge currents that may flow through the
barrier. These current pulses are produced by localized
ionization within the barrier. This is the most sensitive and
reliable indicator of barrier integrity and longevity, and does
not damage the barrier. A device fails the test if five or more
current pulses of 5pC or greater are detected.
Conventional isolation barrier testing applies test voltage far
in excess of the rated voltage to catastrophically break down
a marginal device. A device that passes the test may be
weakened, and lead to premature failure.
APPLICATIONS INFORMATION
Figure 1 shows the ISO150 connected for basic operation.
Channel 1 is configured to transmit data from side B to A.
Channel 2 is set for transmission from side A to B. The R/T pins
for each of the four transceivers are shown connected to the
required logic level for the transmission direction shown. The
transmission direction can be controlled by logic signals
applied to the R/T pins. Channel 1 and 2 can be independently
controlled for the desired transmission direction.
