Description

Devices included in this entry:

Siemens DL1414T (plastic DIP)
Litronix DL1414T (plastic DIP; pictured in thumbnail)
Hewlett-Packard HPDL 1414 (plastic DIP)


The DL1414 is a smaller, less capable version of the well known DL2416 alphanumeric LED display. The DL1414 contains a 7 bit ASCII decoder, display ram, and character generator that provides sophisticated logic control of its four alphanumeric digits. The 1414 lacks the cursor generation and display blanking of the 2416, but the omission of the pins for those functions results in a display that is both smaller and easier to drive than a 2416. This LED display was manufactured by several different companies including Litronix, Siemens, and Hewlett Packard, though the Litronix version of this part is by far the most common.
