Can be used to connect to Din of the next SWITCH. As a result, many SWITCHES can be controlled with one clock and data signal. 6 FLM First Line Marker The marking signal for the first line data of LCD display. The first line of LCD will be selected by the falling edge of LP signal during the high level (FLM). 7 LP Latch Pulse Line data latch pulse will latch content of internal 40-bit shift register at falling edge for one line of display. LP will also increment the display line by one. 8 SCP Serial Clock Pulse Clock used by 40-bit internal shift register of the switch, shifting the display data bit presented at Din at falling edge. 9 Din Data Input Display serial data bit. Note: to map the display data, because of the difference between the number of internal shift register data (40) and the single line of LCD pixels (36), the first four bits of data shifted will be dummy bits. 10 GND 11 VDD Power Power source for logic circuit 12 VLC Power Power source for LCD drive 13 BL-LED (+) Terminal of Backlight LED Anode for common 14 BL-LED (–) Terminal of Backlight LED Cathode for green Ground PRECAUTIONS FOR HANDLING & STORAGE Handling ATTENTION ELECTROSTATIC SENSITIVE DEVICES 1. The IS Series devices are electrostatic sensitive. 2. Limit operating force to keytop to 100.0N maximum, as excessive pressure may damage the LCD device. 3. The IS series devices are not process sealed. 4. If the LCD is accidentally broken, avoid contact with the liquid and wash off any liquid spills to the skin or clothing. 5. Clean cap surface with dry cloth. If further cleaning is needed, wipe with dampened cloth using neutral cleanser and dry with clean cloth. Do not use organic solvent. 6. Recommended soldering time and temperature limits: Do not exceed 70°C at the LCD level. Wave soldering recommended. Preheat temperature 110°C, preheat time 30 seconds, peak temperature 270°C, peak time 5 seconds,1 cycle. Manual soldering recommended. Temperature 390°C for 4 seconds, 2 cycles. 7. Recommendation for backlight color uniformity: use constant current driver. For current limiting resistor method, the power source should be at least twice the backlight LED forward voltage. 8. The VLC voltage should not be applied before logic voltage. If VLC voltage is present before logic voltage, it may cause the driver logic to freeze and damage the LCD, and the driver logic may become damaged. 9. Backlight Forward Current should not exceed the derated Absolute Maximum Forward Current based on the temperature. 10. Excessive images may result after the same image is emitted continuously for an extended period of time. Storage 1. Store in original container and away from direct sunlight. 2. Keep away from static electricity. 3. Avoid extreme temperatures, high humidity, gaseous substances, and all forms of chemical contamination.
