MC26LS30

Dual Differential

(EIA−422−A)/

Quad Single−Ended

(EIA−423−A) Line Drivers

The MC26LS30 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 MC26LS30 is available in a 16−pin surface mount package.

Operating temperature range is −40

°C to +85°C.
