TMP05/TMP06
TMP05 OUTPUT
The TMP05 has a push-pull CMOS output (Figure 28) and
provides rail-to-rail output drive for logic interfaces. The rise
and fall times of the TMP05 output are closely matched so that
errors caused by capacitive loading are minimized. If load
capacitance is large (for example, when driving a long cable),
an external buffer could improve accuracy.
An internal resistor is connected in series with the pull-up
MOSFET when the TMP05 is operating in one shot mode.

TMP06 OUTPUT
The TMP06 has an open-drain output. Because the output
source current is set by the pull-up resistor, output capacitance
should be minimized in TMP06 applications. Otherwise,
unequal rise and fall times skew the pulse width and introduce
measurement errors.
