Four Character Smart Alphanumeric Displays

Currently Viewing:

These are 3.7 mm (0.145 inch) four character 5 x 7 dot matrix displays driven by an on-board CMOS IC. These displays are pin for pin compatible with the HPDL-1414. The IC stores and decodes 7-bit ASCII data and displays it in an easy to read 5 x 7 font. Multiplexing and LED drive circuitry is also included in the display, and fast setup and hold times allow it to interface easily with common microprocessors.
The address and data inputs can be directly connected to microprocessor address and data buses.
The difference 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.
