BL1555 Description
The BL1555 is a Dual Wide-Bandwidth, fast singlepole 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.
