Working Principles
The SN74STV16857DGGRG4 is a bidirectional bus transceiver that enables data transfer between two buses. It operates by receiving data from one bus and transmitting it to the other, or vice versa. The direction of data flow is controlled by the DIR pin. When the DIR pin is high, data is transmitted from Bus A to Bus B, and when the DIR pin is low, data is transmitted from Bus B to Bus A. The OEAB and OEBA pins control the output enable function, allowing the outputs to be tri-stated for bus isolation.
