Working Principles

The SN74ALVCH162334DLR utilizes a combination of CMOS and BiCMOS technologies to achieve bidirectional voltage translation. It consists of two 16-bit ports, Port A and Port B, which can operate at different voltage levels. The device uses level-shifting circuitry to translate the logic levels between these ports.

When the Output Enable (OE) pin is low, the device is enabled, and the data from Port A is translated to Port B or vice versa, depending on the direction of communication. The 3-state outputs allow multiple devices to be connected to the same bus without interfering with each other.
