SN74ALVC164245KR Description

The SN74ALVC164245KR from Texas Instruments is a high-performance, bidirectional voltage-level translator designed for mixed-voltage systems. This 16-bit (dual 8-bit) translator operates with VCCA (2.3V–3.6V) and VCCB (3V–5.5V), enabling seamless interfacing between low-voltage and higher-voltage logic families. Packaged in a 56-ball BGA, it is optimized for space-constrained applications. Although marked as Obsolete, it remains a reliable choice for legacy designs requiring robust voltage translation with minimal propagation delay. The device supports bidirectional data flow, making it versatile for bus isolation and voltage matching in multi-voltage environments.
