Advance Information

Dual Differential (EIA-422-A)/

Quad Single-Ended

(EIA-423-A) Line Drivers

The AM26LS30 is a low power Schottky set of line drivers which can be

configured as two differential drivers which comply with EIA–422–A

standards, or as four single–ended drivers which comply with EIA–423–A

standards. A mode select pin and appropriate choice of power supplies

determine the mode. Each driver can source and sink currents in excess of

50 mA.

In the differential mode (EIA–422–A), the drivers can be used up to

10 Mbaud. A disable pin for each driver permits setting the outputs into a

high impedance mode within a

±10 V common mode range.

In the single–ended mode (EIA–423–A), each driver has a slew rate

control pin which permits setting the slew rate of the output signal so as to

comply with EIA–423–A and FCC requirements and to reduce crosstalk.

When operated from symmetrical supplies (

±5.0 V), the outputs exhibit zero

imbalance.

The AM26LS30 is available in a 16–pin plastic DIP and surface mount

package. Operating temperature range is –40

° to +85°C.
