. A SD_MODE select pin determines the Shutdown Mode for the LD and MH packages, whether it is an Asserted High or an Asserted Low device, to activate
shutdown.
. The SD_MODE select pin is not available with the MM and ITL packaged devices. Shutdown occurs only with a low assertion.
Typical Application
20051001
Note: MM and ITL packaged devices are active low only; Shutdown Mode pin is internally tied to GND.
