SN55LVDS31J

The SN55LVDS31J is designed as one kind of high-speed differential line drivers,SN55LVDS31J has some features:(1)pin compatible with AM26LS31, MC3487, and A9638;(2)low-voltage TTL (LVTTL) logic input levels;(3)bus-terminal ESD protection exceeds 8 kV;(4)cold sparing for space and high reliability applications requiring redundancy;(5)driver at high impedance when disabled or with VCC=0;(6)power dissipation 25 mW typical per driver at 200 MHz;(7)operate from a single 3.3-V supply;(8)operate from a single 3.3-V supply;(9)typical output voltage rise and fall times of 500 ps(400 Mbps);(10)low-voltage differential signaling with typical output voltage of 350 mV and 100-W load.

The intended application of SN55LVDS31J and signaling technique is both point-to-point and multidrop (one driver and multiple receivers) data transmission over controlled impedance media of approximately 100 W. The transmission media may be printed-circuit board traces, backplanes, or cables. The ultimate rate and distance of data transfer is dependent upon the attenuation characteristics of the media and the noise coupling to the environment.

The absolute maximum ratings of the SN55LVDS31J can be summarized as:(1)supply voltage range:0.5 V to 4 V;(2)input voltage range:0.5 V to VCC +0.5 V;(3)continuous total power dissipation:see dissipation rating table;(4)lead temperature 1,6 mm (1/16 inch) from case for 10 seconds:260°C;(5)storage temperature range:65°C to 150°C.
