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.
