Product Overview
The SN74LVTH18652APM from Texas Instruments is a high-performance 18-bit registered bus transceiver designed for 3.3-V VCC operation. It combines D-type latches and D-type flip-flops to allow for transparent, latched, or clocked data flow. The device is ideal for driving high-capacitance backplanes and is compatible with mixed-voltage systems (5-V tolerant inputs). Packaged in a compact 64-pin LQFP (10x10 mm), it offers a space-saving solution for advanced communication and computing systems.
