Working Principles

The SN75155DG4 is designed to convert TTL/CMOS logic levels to differential bus signals. It operates by receiving TTL/CMOS logic level inputs (A and B) and converting them into differential outputs (Y and Z). The driver output (D) can be enabled or disabled using the DE pin, while the receiver output (Y) can be enabled or disabled using the RE pin. This allows for flexible control of the device's operation.
