Operation
STM1066
2
Operation
The STM1066 connects or disconnects the output OUT, from the V pin based on the
IN
logical combination of the enable input (EN), the inhibit input (INH), and the supply voltage
level, V (see Table 2 or Figure 11 for more details).
CC
2.1
Output, OUT
If the enable input is in a logic high state and inhibit input is in a logic low state, the output
will be connected to V input as V rises above the V voltage threshold. Otherwise, the
IN
CC
TH+
output is connected to ground GND. The output is current limited (see Table 5).
2.2
2.3
Enable input, EN
A Logic low on the enable input disconnects the output from V and disables the device,
which enters a standby mode with very low current consumption (see Table 5).
IN
Inhibit input, INH
A logic high on the inhibit input disconnects the output from V .

Maximum ratings
Stressing the device above the rating listed in the “Absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.

DC and AC characteristics
This section summarizes the operating measurement conditions and the DC and AC
characteristics of the device. The parameters in the DC and AC characteristics tables that
follow are derived from tests performed under the measurement conditions summarized in
Table 4: Operating and AC measurement conditions. Designers should check that the
operating conditions in their circuit match the operating conditions when relying on the
quoted parameters.

2. Guaranteed by design.
3. For VCC below VTH-, the output remains low down to VCC = 1 V. Below VCC = 1 V the voltage VIN must be less than
OUT-OL (max.) to guarantee output low voltage less than 0.3 V.
