SLLS833A –MAY 2007–REVISED APRIL 2013

DUAL DIFFERENTIAL DRIVERS AND RECEIVERS

Check for Samples: SN7534050, SN7534051

FEATURES

• Meet or Exceed Standards TIA/EIA-422-B and • Receiver Input Sensitivity: ±200mV

ITU Recommendation V.11

• Receiver Input Impedance: 12 kΩ Min

• Operate From Single 5-V Power Supply

• Driver 3-State Outputs

• Driver Positive and Negative Current Limiting

• Receiver 3-State Outputs (SN7534050 Only)

DESCRIPTION

The SN7534050 and SN7534051 dual differential drivers and receivers are monolithic integrated circuits

designed to meet the requirements of ANSI standards TIA/EIA-422-B and ITU Recommendations V.11.

The driver outputs provide limiting for both positive and negative currents and thermal shutdown protection from

line fault conditions on transmission bus line.

The SN7534050 combines dual 3-state differential drivers and dual 3-state differential input receivers. The

drivers and receivers have active-high and active-low enables, respectively which can be externally connected

together to function as direction control. SN7534051 drivers each have an individual active-high enable.
