DS26LV31T 3V Enhanced CMOS Quad Differential Line Driver

Check for Samples: DS26LV31T

FEATURES

• Standard Microcircuit Drawing (SMD) 5962-

98584

• Industrial Product Meets TIA/EIA-422-B (RS-

422) and ITU-T V.11 Recommendation

DESCRIPTION

• Military Product Conforms to TIA/EIA-422-B

The DS26LV31T is a high-speed quad differential

(RS-422)

CMOS driver that meets the requirements of both

• Interoperable with Existing 5V RS-422

TIA/EIA-422-B and ITU-T V.11. The CMOS

Networks

DS26LV31T features low static I

of 100 μA MAX

which makes it ideal for battery powered and power

• Industrial and Military temperature Range

conscious applications.

• Guaranteed V

of 2V min Over Operating

Differential outputs have the same V

Conditions

(≥2V) as the 5V version.

• Balanced Output Crossover for Low EMI

(Typical Within 40 mV of 50% Voltage Level)

The EN and EN* inputs allow active Low or active

High control of the TRI-STATE outputs. The enables

• Low Power Design (330 μW @ 3.3V static)

are common to all four drivers. Protection diodes

• ESD ≥ 7 kV on Cable I/O Pins (HBM)

protect all the driver inputs against electrostatic

• Guaranteed AC Parameter:

discharge. Outputs have enhanced ESD protection

providing greater than 7 kV tolerance. The driver and

– Maximum Driver Skew: 2 ns

enable inputs (DI, EN, EN*) are compatible with low

– Maximum Transition Time: 10 ns

voltage LVTTL and LVCMOS devices.

• Pin Compatible with DS26C31

• Available in SOIC and CLGA Packaging
