Quad Differential Line Driver

Currently Viewing:

These line drivers are similar to the popular 26LS31 device, but without the enable function. These line drivers provide the additional supply voltage range necessary for use in many industrial control applications. AEIC-2631-S16 supports RS-422A, and allows use of supplies up to 30V. Output voltage swings up to VCC -2V are typical. The outputs are protected against shorts to ground by a two-fold scheme of current limiting and thermal shutdown.

Thermal shutdown is accomplished by monitoring junction temperature and comparing this to a band gap reference on chip. Input hysteresis of about 0.5V provides good noise margin, even in noisy industrial control environments. Input to output propagation delays of less than 200ns are typical for rising and falling edges of the input waveform, measured to the zero crossing of the differential outputs.

This part is available in 16L SOIC (Pb-free) package.
