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.
