Product data sheet
7.1 MUX select (SEL) function
7.2 Shutdown function
Refer to
The CBTL03SB212 uses 3.3 V power supply. All signal paths are implemented using
high-bandwidth pass-gate technology, are bidirectional and no clock or reset signal is
needed for the multiplexer to function.
The switch position is selected using the select signal (SEL). The detailed operation is
described in
The internal multiplexer switch position is controlled by the logic inputs SEL as described
below.
Table 3.
The CBTL03SB212 provides a shutdown function to minimize power consumption when
the application is not active but power to the CBTL03SB212 is provided. Pin XSD_N
(active LOW) puts all channels in Off mode (non-conducting high-impedance state) while
reducing current consumption to near-zero.
