Working Principles
The SN74CB3T3257PWG4 is a 4-bit FET bus switch that allows bidirectional signal switching between four channels. It operates by controlling the FET switches connected to each channel using the OE# and Channel Select pins. When the OE# pin is low, the outputs are enabled, and the selected channel is connected to the I/O pin. Conversely, when the OE# pin is high, all outputs are disabled.
