SN74AVC1T45DCKRG4

Translators, Level Shifters Overview

The SN74AVC1T45DCKRG4 is a single-channel, non-inverting bidirectional voltage-level translator manufactured by Texas Instruments. It operates with dual configurable power rails (VCCA and VCCB) ranging from 1.2 V to 3.6 V, enabling universal low-voltage translation between nodes such as 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V. The device features a propagation delay of 5.6 ns, supports data rates up to 500 Mbps, and includes Ioff circuitry for partial power-down applications. It is housed in a 6-pin SC-70 package and functions within an operating temperature range of -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Supports bidirectional voltage translation between independent 1.2 V to 3.6 V power domains
