SNx5176B Differential Bus Transceivers
1 Features 3 Description
The SN65176B and SN75176B differential bus
1
• Bidirectional Transceivers
transceivers are designed for bidirectional data
• Meet or Exceed the Requirements of ANSI
communication on multipoint bus transmission lines.
Standards TIA/EIA-422-B and TIA/EIA-485-A
They are designed for balanced transmission lines
and ITU Recommendations V.11 and X.27
and meet ANSI Standards TIA/EIA-422-B and
TIA/EIA-485-A and ITU Recommendations V.11 and
• Designed for Multipoint Transmission on
X.27.
Long Bus Lines in Noisy Environments
• 3-State Driver and Receiver Outputs
The SN65176B and SN75176B devices combine a 3-
state differential line driver and a differential input line

receiver, both of which operate from a single 5-V
• Wide Positive and Negative Input/Output Bus
power supply. The driver and receiver have active-
Voltage Ranges
high and active-low enables, respectively, that can be
• ± 60-mA Max Driver Output Capability
connected together externally to function as a
direction control. The driver differential outputs and
• Thermal Shutdown Protection
the receiver differential inputs are connected
• Driver Positive and Negative Current Limiting
internally to form differential input/output (I/O) bus
• 12-kΩ Min Receiver Input Impedance
ports that are designed to offer minimum loading to
the bus when the driver is disabled or V

• ± 200-mV Receiver Input Sensitivity
ports feature wide positive and negative common-
• 50-mV Typ Receiver Input Hysteresis
mode voltage ranges, making the device suitable for
• Operate From Single 5-V Supply
party-line applications.
The driver is designed for up to 60 mA of sink or
