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.
