PACKAGE
8 Lead Plastic DIP
The CA3165 is a single chip electronic switching circuit
intended primarily for ignition applications. It includes an
oscillator that is amplitude-modulated by the rotor teeth of a
distributor, a detector that develops the positive going modu-
lation envelope, a Schmitt trigger that eliminates switching
uncertainties. Both types include two complementary high
current switched outputs for driving power transistors requir-
ing up to 120mA. The CA3165E also includes two comple-
mentary low current outputs that incorporate internal current
limiting and a non-inverting output amplifier with uncommit-
ted input capable of switching 27mA.
The CA3165 is supplied in the 8 lead dual-in-line plastic
package (E suffix) and in the 14 lead dual-in-line plastic
package (E1 suffix).
