5. The strobe signal has negative logic regardless of the setting of pin 5.
6. When the output device (such as a numeric display) does not have a pull-up resistor, it is necessary to
add a pull-up resistor between the + terminal of the power supply and each data (0 to 15) and strobe (0 to
15) terminal.
