bl1558
高带宽,四通道,单刀双掷
产品简介
the bl1558 is a 4-channel single-pole double-throw (spdt) analog switch with two control inputs，which is designed to operate from 1.8 to 5.5v. this device is also known as a dual double-pole double-throw (dpdt) configuration with two logic control inputs. the bl1558 can handle both analog and digital signals. it features high-bandwidth (400mhz) and low on-resistance(4ω typ).
