PRODUCTION DATA.
The SHDN pin of the LM284x-Q1 is designed so that it may be controlled using 2.3 V or higher logic signals. If the shutdown function is not to be used the SHDN pin may be tied to VIN. This input must not be allowed to float
The maximum voltage to the SHDN pin should not exceed 42 V. If the use of a higher voltage is desired due to system or other constraints it may be used; however, a 100 kΩ or larger resistor is recommended between the applied voltage and the SHDN pin to protect the device.
