APPLICATION INFORMATION
latch-up avoidance
Junction-isolated CMOS circuits have an inherent parasitic PNPN structure that can function as an SCR. Under
certain conditions, this SCR may be triggered into a low-impedance state, resulting in excessive supply current.
To avoid such conditions, no voltage greater than 0.3 V beyond the supply rails should be applied to any pin.
In general, the operational amplifier supplies should be applied simultaneously with, or before, application of
any input signals.
output stage considerations
The amplifier’s output stage consists of a source-follower-connected pullup transistor and an open-drain
pulldown transistor. The high-level output voltage (V
OH
) is virtually independent of the I
DD
selection and
increases with higher values of V
DD
and reduced output loading. The low-level output voltage (V
OL
) decreases
with reduced output current and higher input common-mode voltage. With no load, V
OL
is essentially equal to
the potential of V
DD–
/GND.
supply configurations
Even though the TLC252/25_2C series is characterized for single-supply operation, it can be used effectively
in a split-supply configuration if the input common-mode voltage (V
ICR
), output swing (V
OL
and V
OH
), and supply
voltage limits are not exceeded.
circuit layout precautions
The user is cautioned that whenever extremely high circuit impedances are used, care must be exercised in
layout, construction, board cleanliness, and supply filtering to avoid hum and noise pickup, as well as excessive
dc leakages.
