CDP1872C, CDP1874C, CDP1875C March 1997 High-Speed 8-Bit Input and Output Ports Description The CDP1872C, CDP1874C and CDP1875C devices are high-speed 8-bit parallel input and output ports designed for use in the CDP1800 microprocessor system and for general use in other microprocessor systems. The CDP1872C and CDP1874C are 8-bit input ports; the CDP1875C is an 8-bit output port. These devices have exible capabilities as buffers and data latches and are reset by CLR input when the data strobe
