Abstract Description CONTROL A B Modes A to B B to A Isolation

Pin Description

Problem? What happens if there are inputs coming into both the A and B bus and you are also trying to pass the A bus to the B bus.

Tri-State Buffer CONTROL Modes A = A B = 0 or A = 0 B = B A A B B

Pin Description

How they work together… Octal Bus Transceiver Modes A to B B to A Isolation A B Tri-State Buffer

Demonstration The purpose of the circuit that I built was to demonstrate, using 7-Segment displays, the behavior of the Octal Bus Transceiver.
