SN74LVC2T45DCTR TI Dual-Bit Voltage-Level Translator | SM8 | 1.65-5.5V, 500Mbps

Product Overview

The SN74LVC2T45DCTR is a dual-bit non-inverting bus transceiver from Texas Instruments, designed for asynchronous communication between two voltage nodes. It features two independent supply voltages (VCCA and VCCB), each operating from 1.65 V to 5.5 V, enabling bidirectional level translation for a wide range of logic levels. The device supports data rates up to 500 Mbps, making it suitable for high-speed signal translation in mixed-voltage systems. Housed in the compact SM8 (DCT) package, it is ideal for space-constrained applications.
