GENERAL:
The device LTM2881wx-y is an isolated full-duplex RS485/RS422 μModule
transceiver with isolated power. Logic and Isolated side common are separated
by galvanic isolation. Internal “chips” are connected to a PCB substrate(leadframe) that is molded into the enclosure.
The device LTM2882wx-y is an isolated full-duplex RS232 μModule transceiverwith isolated power. Logic and Isolated side common are separated by galvanic
isolation. Internal “chips” are connected to a PCB substrate (leadframe) thatis molded into the enclosure.
The devices LTM2883wx-yz, LTM2886wx-yz, and LTM2887wx-yz are complete Serial
Peripheral Interface Bus (SPI) or Inter-IC Bus (I2C) μModule isolators withisolated power. Logic and Isolated side common are separated by galvanic
isolation. Internal “chips” are connected to a PCB substrate (leadframe) thatis molded into the enclosure.
The device LTM2889wx-y is an isolated CAN Bus μModule transceiver withisolated power. Logic and Isolated side common are separated by galvanic
isolation. Internal “chips” are connected to a PCB substrate (leadframe) thatis molded into the enclosure.
The device LTM2884wx is an Isolated USB Transceiver with Isolated Power. Logicand Isolated side common are separated by galvanic isolation. Internal“chips” are connected to a PCB substrate (leadframe) that is molded into theenclosure.

ENGINEERING CONSIDERATIONS (NOT FOR FIELD REPRESENTATIVE'S USE):
Use - For use only in products where the acceptability of the combination isdetermined by Underwriters Laboratories Inc.
*USR indicates this product was investigated under the UL Standard for Safety
for Optical Isolators, UL 1577, Fifth Edition, revised July 6, 2023.
CNR indicates this product was investigated under the Canadian Certification
Notice, CSA Component Acceptance Service No. 5A dated January 23, 1998.
Conditions of Acceptability - Each device shall be reviewed with respect tothe following conditions of acceptability:
1.

The capability of the device to control a load has not been
investigated.

2.

These devices should be installed in a suitable end product enclosure.

3.

The maximum operating (ambient) temperature, as noted in the ratings
table, shall not be exceeded.

4.

For single protection devices, the insulation to the case has not been
evaluated. For double protection devices, the insulation to the casehas been evaluated to the isolation voltage specified in the ratings
table.

5.

In addition to meeting single protection requirements, double protection
optical isolators have also been investigated for use in up to 250 V,
50/60 Hz circuits in audio, video, and similar equipment in applications
in which breakdown of the optical isolator may result in a risk of fire,electrical shock, or injury to persons.
