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.

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.

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 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.
