Overview

o CO CO CO Display Drivers :E Q "o- CO CO I"- DM7880/DM8880 high voltage 7-segment decoder/driver :E (for driving Sperry and Panaplex IITM displays) Q general description The DM7880/DM8880 is custom designed to decode four lines of BCD and drive a gas-filled seven-segment display tube.
The design employs a 112-bit read-only memory which provides BCD Input to full hexadecimal output decoding In the standard DM7880/DM8880 product.
For applications desiring other fonts, or not using standard BCD coding, the ROM contents can be custom modified to produce any 16 output displays for the 16 binary Input combinations.
Each output constitutes a sWltchable, adjustable current sink which p...
