This document describes the TLF6561 DM74184 and DM74185A BCD-to-Binary and Binary-to-BCD Converters. These converters allow direct read-out of converted codes and demonstrate the versatility of read-only memory. The converters can be cascaded, have an overriding enable input, and open-collector outputs.
This document describes the monolithic DM74184 and DM74185A converters derived from 256-bit read-only memories. The DM74184 performs BCD-to-binary conversion with optional generation of BCD 9's or 10's complements, while the DM74185A performs binary-to-BCD conversion. Both devices feature open-collector outputs and are cascadable for N-bit applications.
