What voltage ranges does it support?

Both the A and B ports support any supply voltage from 1.65V to 5.5V, allowing for flexible translation between 1.8V, 2.5V, 3.3V, and 5V nodes.

How is the direction controlled?

The direction is controlled by the DIR pin. When DIR is LOW, data flows from B to A; when DIR is HIGH, data flows from A to B.

What are the key design considerations?

Designers must ensure proper power-up sequencing (GND first, then VCCA) and manage the DIR pin to avoid bus contention, as the device lacks a dedicated OE pin.

What is the sourcing status?

The part is currently active and widely available with high stock levels, making it a reliable choice for long-term designs.

What is the pinout of SN74LVC2T45DCUR?

Use the SN74LVC2T45DCUR datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about SN74LVC2T45DCUR pinout to locate pins, power rails, and interface signals before layout.
