Four Character Smart Alphanumeric Displays

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.
