Description

This sunlight viewable 5 x 7 LED four-character display

is contained in 12 pin dual-in-line packages designed

for displaying alphanumeric information. The display is

designed with on-board CMOS integrated circuits. Two

CMOS ICs form an on-board 28-bit serial-in/parallel-out

shift register with constant current output LED row driv-

ers. Decoded column data is clocked into the on-board

shift register for each refresh cycle. Full character display

is achieved with external column strobing.

Typical Applications

• Avionics

• Communication systems

• Fire control systems

• Radar systems

Electrical Description The display contains four 5 x 7 LED dot matrix characters and two CMOS integrated circuits, as shown in Figure 1. The two CMOS integrated circuits form an on-board 28 bit serial-in/parallel-out shift register that will accept standard TTL logic levels. The Data Input, pin 12, is connected to bit position 1 and the Data Output, pin 7, is connected to bit position 28. The shift register outputs control constant current sinking LED row drivers.

ESD Susceptibility Night Vision Lighting The display has an ESD susceptibility ratings of CLASS 3 of MIL-STD-883E, HBM. It is recommended that normal CMOS handling precautions be observed with these devices. When used with the proper NVG/DV filters, HCMS-235x display may be used in night vision lighting applications. For a list of NVG/DV filters and a discussion on night vision lighting technology, refer to Application Note 1030, LED Displays and Indicators and Night Vision Imaging System Lighting.
