QUADRUPLE DIFFERENTIAL LINE DRIVER
SLLS114I – JANUARY 1979 – REVISED FEBRUARY 2006
• Meets or Exceeds the Requirements of ANSI
TIA/EIA-422-B and ITU
• Operates From a Single 5-V Supply
• TTL Compatible
• Complementary Outputs
• High Output Impedance in Power-Off
Conditions
• Complementary Output-Enable Inputs
The AM26LS31 is a quadruple complementary-output
line driver designed to meet the requirements of ANSI
TIA/EIA-422-B and ITU (formerly CCITT)
Recommendation V.11. The 3-state outputs have
high-current capability for driving balanced lines such
as twisted-pair or parallel-wire transmission lines, and
they are in the high-impedance state in the power-off
condition. The enable function is common to all four
drivers and offers the choice of an active-high or
active-low enable (G, G) input. Low-power Schottky
circuitry reduces power consumption without
sacrificing speed.
