HDLX-1414 Series Four Character Smart Alphanumeric Displays Data Sheet Description Features These are 3.7 mm (0.145 inch) four character 5 x 7 dot matrix Dot matrix replacement of HPDL-1414 displays driven by an on-board CMOS IC. These displays are Smart alphanumeric display pin for pin compatible with the HPDL-1414. The IC stores and Built-in RAM, ASCII decoder, and LED drive circuitry decodes 7-bit ASCII data and displays it in an easy to read 128 ASCII character set 5 x 7 font. Multiplexing and LED drive circuitry is also included in the display, and fast setup and hold times End stackable allow it to interface easily with common microprocessors. Categorized for luminous intensity Yellow and Green categorized for color The address and data inputs can be directly connected to microprocessor address and data buses. Low power and sunlight viewable AlGaAs versions The HDLX-1414 off ers a larger character set than the Wide viewing angle (50 typical) HPDL-1414. Lower case letters and special symbols are now off ered, made possible by the 5 x 7 dot matrix character layout. The diff erence between the sunlight viewable HDLS-1414 and the low power HDLU-1414 lies in the brightness level. The sunlight viewable version is internally set to provide high intensity characters. The low power version uses the same bright LED technology, but reduces the current through each LED to a much lower level, and maintains an intensity comparable to the HDLO-1414.
