FEATURES
DESCRIPTION
The DS3487 quad RS-422 driver features four
2
• Four Independent Drivers
independent drivers which comply with EIA Standards
• TRI-STATE Outputs
for the electrical characteristics of balanced voltage
• Fast Propagation Times (typ 10 ns)
digital interface circuits. The outputs are TRI-STATE
structures which are forced to a high impedance state
• TTL Compatible
when the appropriate output control pin reaches a
• 5V Supply
logic zero condition. All input pins are PNP buffered
• Output Rise and Fall Times Less than 15 ns
to minimize input loading for either logic one or logic
zero inputs.
• Pin Compatible with DS8924 and MC3487
