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.
• Operates as Two Differential EIA−422−A Drivers, or Four
Single−Ended EIA−423−A Drivers
• High Impedance Outputs in Differential Mode
• Short Circuit Current Limit In Both Source and Sink Modes
• ±10 V Common Mode Range on High Impedance Outputs
• ±15 V Range on Inputs
• Low Current PNP Inputs Compatible with TTL, CMOS, and MOS
Outputs
• Individual Output Slew Rate Control in Single−Ended Mode
• Replacement for the AMD AM26LS30 and National Semiconductor
DS3691
• Pb−Free Packages are Available

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
Devices should not be operated at these limits. The “Recommended Operating Conditions” table provides conditions for actual device operation.
