SN74ALVC164245DL Description

The SN74ALVC164245DL from Texas Instruments is a high-performance, dual-supply bidirectional voltage-level translator designed for seamless interfacing between mixed-voltage systems. This 16-bit (2x8) translator operates with VCCA (2.3V–3.6V) and VCCB (3V–5.5V), enabling robust signal conversion between low-voltage and higher-voltage domains. Packaged in a 48-pin SSOP (Shrink Small-Outline Package), it is ideal for space-constrained applications. The device supports bidirectional data flow with automatic direction sensing, eliminating the need for additional control signals. Its 74ALVC series architecture ensures low power consumption, high-speed operation (up to 3.7ns propagation delay), and superior noise immunity, making it suitable for high-speed digital systems.
