TCS3771 − ApplicationInformation
V_BUS in the above figures refers to the I²C bus voltage which is
either V_DD or 1.8V. Be sure to apply the specified I²C bus voltage
shown in the Available Options table for the specific device
being used.
The I²C signals and the Interrupt are open-drain outputs and
require pull−up resistors. The pull-up resistor (RP) value is a
function of the I²C bus speed, the I²C bus voltage, and the
capacitive load. The ams EVM running at 400kbps, uses 1.5kΩ
resistors. A 10kΩ pull-up resistor (RPI) can be used for the
interrupt line.
PCB Pad Layout
Suggested PCB pad layout guidelines for the Dual Flat
No-Lead (FN) surface mount package are shown in Figure 46.
Note(s) and/or Footnote(s):
1. All linear dimensions are in millimeters.
2. This drawing is subject to change without notice.
3. Pads can be extended further if hand soldering is needed.
