CDP1852C datasheet(2/9 Pages) INTERSIL

2 / 9 page

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).
