CDP1852 - Byte-Wide Input/Output Port

CDP1852 Description

TM CDP1852, CDP1852C Byte-Wide Input/Output Port .
The CDP1852 and CDP1852C are parallel, 8-bit, mode-programmable input/output ports.

CDP1852 Features

* Static Silicon-Gate CMOS Circuitry
* Parallel 8-Bit Data Register and Buffer
* Handshaking Via Service Request Flip-Flop
* Low Quiescent and Operating Power
* Interfaces Directly with CDP1800-Series Microprocessors
* Single Voltage Supply
* F

CDP1852 Applications

* The mode control is used to program the device as an input port (mode = 0) or as an output port (mode = 1). The SR/SR output can be used as a signal to indicate when data is ready to be transferred. In the input mode, a peripheral device can strobe data into the CDP1852, and microprocessor can read
