Working Principles

The SN74ALVTH16244GR is a bidirectional bus transceiver that allows data transmission between two buses with different voltage levels. It uses advanced low-voltage CMOS technology to achieve high-speed operation while operating at low voltages.

The direction of data flow is controlled by the DIR (Direction) pin. When DIR is set to logic low, data flows from the A bus to the B bus. Conversely, when DIR is set to logic high, data flows from the B bus to the A bus.

The OE1 (Output Enable 1) and OE2 (Output Enable 2) pins control the enable/disable state of the outputs. When either OE1 or OE2 is set to logic high, the outputs are disabled, effectively isolating the A and B buses.
