The CDP1853 and CDP1853C are 1 of 8 decoders designed for use in general purpose microprocessor systems. These devices, which are functionally identical, are specifically designed for use as gated N-bit decoders and interface directly with the 1800-series microprocessors without additional components. The CDP1853 has a recommended operating voltage range of 4V to 10.5V, and the CDP1853C has a recommended operating voltage range of 4V to 6.5V.
