Table 2: TMC457-BC Pin Out
9.1.1
Some inputs have weak on-chip pull-up resp. weak pull-down resistors. The resistance of these is
within the range of 10 kOhm (min.) … 45 kOhm (max.)
9.1.2
Ceramic capacitors of 100nF capacitance should be connected as close as possible at each 1V5
power supply pin and at each 3V3 power supply pin. Alternatively, two power planes – one power plane
for +1V5 (V15) and one power plane for +3V3 (V33) can be used.
