sn75176 schematic

Hi all,

How can i connect the SN75176 interface to my PIC18F4620?

What is TTL? does it mean that the voltage is between 0V and 5V?

My peripheral device(AX-12 actuator) has the following requirements:serial communication(TTL), half duplex protocol, 1Mbips data rate, and input voltage(7V-10V).

did i choose the right devices to communicate with the AX-12?

Thanks
