Overview
The 74ALVC164245DL/C4118, produced by NXP USA Inc., is a high-performance, low-power, low-voltage, Si-gate CMOS device. It is designed as a 16-bit (dual octal) dual supply translating transceiver, featuring non-inverting 3-state bus compatible outputs in both send and receive directions. This device is particularly useful for interfacing between 3 V and 5 V buses in mixed supply environments, making it suitable for systems that require level shifting between different voltage domains.
