A CLEAR control is provided for resetting the port’s register
(DO0-DO7 = 0) and service request flip-flop (input mode:
SR/ SR = 1 and output mode: SR/SR = 0).
The CDP1852 is functionally identical to the CDP1852C.
The CDP1852 has a recommended operating voltage range
of 4 to 10.5 volts, and the CDP1852C has a recommended
operating voltage range of 4 to 6.5 volts.
The CDP1852 and CDP1852C are supplied in 24-lead,
hermetic, dual-in-line ceramic packages (D suffix), in 24-lead
dual-in-line plastic packages (E suffix). The CDP1852C is
also available in chip form (H suffix).
