-55°C to 105°C Rated Isolated Transceivers with Power

Isolated RS485 & RS232 µModule Transceivers Now Specified for -55°C to 105°C for Military & Automotive Applications

MILPITAS, CA – March 26, 2012 – Linear Technology Corporation introduces automotive
(H-grade) and high reliability military (MP-grade) versions of the LTM2881 and LTM2882, isolated µModule® transceivers which guard against large ground-to-ground differentials and common-mode transients in RS485 and RS232 networks. The LTM2881 single RS485 and LTM2882 dual RS232 transceivers break ground loops by isolating the logic level interface and line transceiver using internal inductive signal isolation. This allows for a much larger
common- mode voltage range plus superior common mode rejection >30kV/us. A low EMI, 1W DC/DC converter generates the power supplies for driving RS485 or RS232 levels and provides an additional isolated 5V supply output for powering any supporting external components. With 2,500VRMS of galvanic isolation, onboard secondary power, and fully compliant transmitters and receivers, the LTM2881 and LTM2882 require no external components, providing complete, compact µModule solutions for isolated serial data communications. The H- and MP-grade versions are guaranteed over operating ambient temperatures from -40°C to 105°C and -55°C to 105°C, respectively. More on Linear Technology’s military grade flow is available at
Two versions of the LTM2881 and LTM2882 are available to support 3.3V and 5V input supply voltages. Both devices are offered in low profile 11.25mm x 15mm surface mount LGA
(H-grade only) and BGA packages. All integrated circuits and passive components are housed in this Linear Technology, RoHS-compliant µModule package. Visit for product selection information.
