Product data sheet
7.1 Function selection
7.2 Shutdown function
Refer to
Table 3.
X = Don’t care.
The CBTL04082A/B provides a shutdown function to minimize power consumption when
the application is not active, but power to the CBTL04082A/B is provided. Pin XSD01 and
XSD23 (active HIGH) places channel 0/1 and 2/3 (respectively) in high-impedance state
(non-conducting) while reducing current consumption to near-zero.
