Low Voltage SPDT Mux /

Demux Analog Switch

The NLAS3157 Mux / Demux Analog Switch is an advanced high−

speed single−pole double−throw (SPDT) CMOS switch. It can be used

as an analog switch or as a low−delay bus switch. Break−before−make

switching prevents both switches being enabled simultaneously. This

eliminates signal disruption during switching. The control input, S, is

independent of supply voltage line switch in an ultra−small footprint.
