Working Principles

The SN74ABT623PWG4 is a bus transceiver that enables bidirectional data transfer between two buses. It operates by using the output enable (OE) control signals to determine the direction of data flow. When OE is low, data can be transferred from Bus A to Bus B, and when OE is high, data can be transferred from Bus B to Bus A. The TTL-compatible inputs and outputs ensure seamless integration with other ICs.
