    Description
    The BL1551 is a Single Wide-Bandwidth, fast single-
    pole double-throw (SPDT) CMOS switch featuring an
    On-Resistance of 2.7 ohm at V
    CC
    =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.
