SN74AVC1T45DBVR TI Translators, Level Shifters

The SN74AVC1T45DBVR from TI is a single‑bit dual‑supply bus transceiver that enables bidirectional voltage‑level translation between any two nodes from 1.2 V to 3.6 V, using two independently configurable power rails. For selection, it supports data rates up to 500 Mbps with a typical propagation delay of just 2.8 ns and ±12 mA output drive at 3.3 V. The direction‑control (DIR) pin defines data flow, and the 3‑state outputs allow bus isolation. Fully specified for partial‑power‑down applications using Ioff, the device limits reverse current when powered down, and the VCC isolation feature puts both ports in a high‑impedance state if either supply is at GND. It operates from −40 °C to +85 °C in a compact SOT‑23‑6 package. In application, it bridges mixed‑voltage domains in smartphones, tablets, IoT sensor modules, portable medical devices, industrial automation, and automotive body electronics, interfacing microcontrollers with peripherals such as sensors, displays, and memory interfaces across voltage nodes of 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V.
