Working Principles

The SN74LVT162240DGVR utilizes LVT technology to perform bidirectional voltage translation. It consists of 16 buffers/drivers that can be independently enabled or disabled using the control inputs. The DIR input determines the direction of data flow, while the OE input enables or disables the outputs.

When the DIR input is set to logic high, the device acts as a buffer, translating the logic levels from the A-side (Group A) to the B-side (Group B). Conversely, when the DIR input is set to logic low, the translation occurs from the B-side to the A-side.

The 3-state outputs allow the device to disconnect from the bus, preventing any interference when other devices are driving the same lines.
