HDSP-0770光电器件的显示器模块-LED字符与数字规格书PDF中文资料

描述 Description

These solid state display devices are designed and tested for use in adverse industrial environments. The character height is 7.4mm (0.29 inch). The numeric and hexadecimal devices incorporate an on-board IC that contains the data memory, decoder and display driver functions.

The numeric devices decode positive BCD logic into characters “0-9”, a “–” sign, decimal point, and a test pattern. The hexadecimal devices decode positive BCD logic into 16 characters,“0-9, A-F.”An input is provided on the hexadecimal devices to blank the display (all LEDs off) without losing the contents of the memory.

The over range device displays “±1” and right hand decimal point and is typically driven via external switch ing transistors.
