Description
The BL1551 is a Single Wide-Bandwidth, fast singlepole
double-throw (SPDT) CMOS switch featuring an
On-Resistance of 2.7 ohm at VCC=5.0V and wide
power supply range from 1.8V to 5.5V. It can be used
as an analog switch or as a low-delay bus switch.
The 300MHz high bandwidth performance supports
the high frequency application.
Break-before-make function for both parts eliminates
signal disruption during switching from preventing
both switches being enabled simultaneously.
