CDP1872C Input Port TERMINAL ASSIGNMENT
High-Speed 8-Bit Input and Output Ports
Features:
Parallel 8-bit input/output register with buffered outputs High-spead data-in to data-out:
85 ns (max.) at Vee = 5 V Flexible applications in microprocessor systems as
buffers and latches High order address-latch capability in CDP1800 series
microprocessor systems Output sink current = 5 mA (min.) at Vee = 5 V 3-state output - CDP1872C and CDP1874C
The RCA-COP1872C, COP1874C and COP1875C devices are high-speed 8-bit parallel input and output ports designed for use in the COP1800 microprocessor system and for general use in other microprocessor systems. The CDP1872C and COP1874C are 8-bit input ports; the COP1875C...
