Avago Technologies unveils the AEIC-7272, AEIC-7273 and AEIC-2631 high-voltage quad differential line drivers that provide up to 30V additional supply voltage targeted at the industrial automation market.

With integrated current limiting and thermal shutdown features, the line drivers protect against shorts to assure highly-reliable operation in harsh environments for industrial encoder and sensor interfaces, industrial programmable logic controllers and servo drive applications.

The line drivers are designed to meet industrial standards for encoder applications. They offer a robust operating temperature range from -55 to 125°C for the AEIC-7272 and AEIC-7273 devices and -40 to 125°C for the AEIC-2631 device. They are all available in industrial standard line driver SOIC packaging. Offering high-impedance buffered inputs with hysteresis, the line drivers provide strong noise margin even in noisy industrial control environments. Avago is exhibiting the line drivers along with its portfolio of motion control and isolation solutions for motor applications, at the MotorTech Japan 2011 trade show in East Hall 1 booth number 1D-103 from July 20-22.

The AEIC-2631 device operates in a wide supply voltage range of 4.75 to 30V and features tri-state outputs. The AEIC-7272 device features tri-state outputs and the AEIC-7273 device features NPN open-collector outputs, and each operates from 3.5 to 30V. The line drivers' thermal shutdown feature is accomplished by monitoring junction temperature and comparing this to a band gap reference on-chip.

Additional features of the AEIC-7272, AEIC-7273 and AEIC-2631 line driver include: 1) 800kHz operation; 2) CMOS and TTL compatible inputs; 3) RS-422A support; and 4) lead-free, 16-pin SOIC package.

Samples and production quantities of the Avago AEIC-7272, AEIC-7273 and AEIC-2631 line drivers are available now through Avago's direct sales channel and worldwide distribution partners.
