The module output pins could require a buffer (see Figure 13) depending on the logic level requirements (see the
section). HCT gates supplied with 5V can be used in a 5V host system with TTL or CMOS inputs (see Figure 13). LVC gates can maybe
be used for output signals if the host input signals are TTL compatible (V
host input signals.
The 74HCT08 gate is also available in a single and dual gate package (74AHCT1G08 and 74AHCT2G08).
Figure 12: Logic levels interface to a 3/3.3V system. A protective 100Ohm resistor is used.
Figure 13: Interface example with logic levels to a 5V system. The gate converting from host 5V output to module input can be
repleced with an LVC gate if the voltage divider is removed.
