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
