DESCRIPTION
Each of the M75176 to M75179 is a semiconductor IC with a built-in differential driver and a built-in differential receiver both of which meet the EIA standards RS-422A and RS-485.

FEATURES
Common
• 5V single power supply
• With output control input (except M75179P)

Driver
• 54Ω terminal resistor connectable between outputs.
• High output impedance at power-OFF time
• Built-in output current limit circuit

Receiver
• High input sensitivity (±200mV max.)
• Hysteresis input (50mV typ.)
• High input impedance (12kΩ min.)
• “H” emitted when input is open (failsafe function)

APPLICATION
   High-speed data transmission interface for digital equipment
