CLEAR 12 13 CS2 TOP VIEW 92C5-27572 CDP1852, CDP1852C TERMINAL ASSIGNMENT Byte-Wide Input/Output Port Features: Static silicon-gate CMOS circuitry Parallel B-bit data register and buffer Handshaking via service request flip-flop Low quiescent and operating power Interfaces directly with CDP1BOO-series microprocessors Single voltage supply Full military temperature range (-55°C to +125°C) The ACA-CDP1852 and CDP1852C are parallel, 8-bit, mode-programmable input/output ports. They are compatible and will interface directly with CDP1800,eries microprocessors. They are also useful as 8-bit address latches when used with the CDP1800 multiplexed address bus and as liD ports in general-purpose applications. The mode control ...
