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° to +85°C.
