Notes:
1. Maximum duration 2 seconds.
2. Maximum allowable power dissipation is derived from V_DD = 5.25 V, V_B = 2.4 V, V_COL = 3.5 V, 20 LEDs ON per character, 20% DF.
3. HCMS-2353 derate above 71°C at 23 mW/°C, R_J-A = 45°C/W.
Derating based on R_PC-A = 35°C/W per display for printed circuit board assembly.


Description

This HCMS-235  sunlight viewable 5 x 7 LED four-character display is contained in 12 pin dual-in-line packages designed for displaying alphanumeric information. The HCMS-235 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 drivers. Decoded column data is clocked into the on-board shift register for each refresh cycle. Full character display is achieved with external column strobing.
