DM8898 - (DM8898 / DM8899) TRI-STATE BCD to Binary/Binary to BCD Converters

Description

These circuits are the TRI-STATE versions of the popular BCD to binary and binary to BCD converters DM74184 and DM74185A respectively They are derived from the 256-bit ROM DM8598 Emitter connections are made to provide direct read out of converted codes at outputs Y8 through Y1 as shown in the truth
