Working Principles

The SN74ALVCH16269DGGR utilizes a combination of CMOS and TTL technologies to achieve voltage level translation. The enable pins control the direction of data flow, allowing bidirectional communication between two voltage domains. When the enable pin is set to a logic high level, the A-side is active, and when it is set to a logic low level, the B-side is active. The IC internally handles the voltage level shifting, ensuring proper signal translation.
