Product Overview
The SN74LVTH162240DL from Texas Instruments is a 16-bit inverting buffer/driver designed for 3.3-V operation with 5-V tolerant inputs and outputs. It is part of the LVTH family, offering low-voltage operation with high drive capability. The device is ideal for driving bus lines or buffering memory address registers. Its flow-through architecture optimizes PCB layout, and the 48-pin SSOP package provides a compact solution for space-constrained applications.
