SN74AXCH2T45DCUR TI Dual-Bit Voltage-Level Translator | 8-VSSOP | 0.65-3.6V, 500Mbps

Product Overview

The SN74AXCH2T45DCUR from Texas Instruments is a dual-bit, non-inverting voltage-level translator designed for bidirectional voltage translation between two independent power-supply voltages. It supports a wide voltage range from 0.65V to 3.6V on both A and B ports, making it ideal for low-voltage and mixed-voltage systems. The device features automatic direction sensing, eliminating the need for a direction control pin. Housed in a compact 8-VSSOP package, it offers high-speed operation up to 500 Mbps and is fully specified for partial-power-down applications using Ioff circuitry.
