LMH2180 is a high speed dual clock buffer designed for portable communications and applications requiring multiple accurate multi-clock systems. It integrates two 75 MHz low noise buffers with independent shutdown pins into a small package.
The LMH2180 dual clock buffer from National Semiconductor provides two independent 75 MHz low‑noise buffers with individual shutdown pins, rail‑to‑rail inputs and outputs, and a gain of one. It is designed for portable communications and other applications that require accurate multi‑clock systems, offering low supply current and rapid recovery for battery‑powered designs.
The device is supplied in a compact 8‑pin LLP package with pin‑access, supports supply voltages from 2.4 V to 5 V, operates over –40 °C to 85 °C, and delivers a typical slew rate of 106 V/µs. Detailed electrical characteristics, pin descriptions, and typical application circuits are provided in the document.
