BL1555

低导通电阻,双通道,单刀双掷

产品简介

The BL1555 is a Dual Wide-Bandwidth, fast single-pole double-throw (SPDT) CMOS switch featuring an On-Resistance of 0.3 ohm at VDD=5V and wide power supply range from 1.65V to 5.5V. It can be used as an analog switch or as a low-delay bus switch.Break-before-make function for both parts eliminates signal disruption during switching from preventing both switches being enabled simultaneously.
