A.2 Design Examples
This section contains design examples for all interfaces on J2, J3, J6, J7 and J8. The connector
type that suits a specific application depends on the needed signal and the preferred interface
type (wires, flexfilm, board-to-board or SMD).
A.2.1 Logic Levels
A 3.0/3.3V host system can be connected directly to the logic level pins (BLUE, UART-TxD /
UART-RxD etc). A serial 100Ω resistor shall be used (see Figure 11) for protection, see Table 12
for logic levels characteristics.
A 5V host system can easily be adjusted to the logic levels. A host system output signal can use
a resistive divider (1.8kΩ/2.2kΩ) to adjust the levels. This is applicable for speeds up to
115.2kBits/s. The divider can be improved by adding a logic buffer (74HCT08) for higher speeds
(see Figure 12). The host system input pins could require a buffer (see Figure 12) depending on
the logic level requirements (see Table 12).
The 74HCT08 gate is also available in a single gate package (74AHCT1G08).
A 5V system with open collector outputs is designed in Figure 13.
