SNJ55LVDS31FK General Description

The SN55LVDS31, SN65LVDS31, SN65LVDS3487, and SN65LVDS9638 devices are differential line drivers that implement the electrical characteristics of low-voltage differential signaling (LVDS). This signaling technique lowers the output voltage levels of 5-V differential standard levels (such as TIA/EIA-422B) to reduce the power, increase the switching speeds, and allow operation with a 3.3-V supply rail. Any of the four current-mode drivers will deliver a minimum differential output voltage magnitude of 247 mV into a 100-Ω load when enabled.

Key Features

Meet or Exceed the Requirements of ANSI TIA/EIA-644 Standard
Low-Voltage Differential Signaling With Typical Output Voltage of 350 mV and 100-Ω Load
Typical Output Voltage Rise and Fall Times of 500 ps (400 Mbps)
Typical Propagation Delay Times of 1.7 ns
Operate From a Single 3.3-V Supply
Power Dissipation 25 mW Typical Per Driver at 200 MHz
Driver at High-Impedance When Disabled or With V_CC = 0
Bus-Terminal ESD Protection Exceeds 8 kV
Low-Voltage TTL (LVTTL) Logic Input Levels
Pin Compatible With AM26LS31, MC3487, and µA9638
Cold Sparing for Space and High-Reliability Applications Requiring Redundancy
