74ALVC164245ZRDR

74ALVC164245ZRDR Description

The 74ALVC164245ZRDR from Texas Instruments is a high-performance, bidirectional voltage-level translator designed for interfacing between mixed-voltage systems. This 16-bit (2x8) translator operates with VCCA (2.3V–3.6V) and VCCB (3V–5.5V), enabling seamless communication between low-voltage and higher-voltage logic families. Packaged in a 54-ball BGA (Tape & Reel), it is optimized for space-constrained, high-density PCB designs. Though marked as Obsolete, it remains relevant for legacy systems due to its robust performance, ROHS3 compliance, and REACH unaffected status. Its MSL 1 (Unlimited) rating ensures reliability in storage and handling.
