Description
The CDP1852/3 and CDP1852C/3 are parallel, 8-bit, mode-programmable input/output ports. They are compatible and will interface directly with CDP1800-Series microprocessors. They are also useful as 8-bit address latches when used with the CDP1800 multiplexed address bus and as I/O ports in general-purpose applications.
