description

The AM26LS31C 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 provide

a 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.

The AM26LS31C is characterized for operation from 0°C to 70°C.

†

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. All voltage values, except differential output voltage V , are with respect to network GND.

2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace

length of zero.
