Identifying a Motolora chip - MC14544?

Howdy folks; I'm trying to identify a Motorola chip for my father - his guess is a 300 baud modem... The chip comes from circuitry which allows folks to remotely control the lights on a runway. All of the breakers/generators are in a little shed at the end of the runway, but there is a controller board in the tower to allow you to turn on lights without having to trek down to the shed... Unfortunately said controller is broken, and my old man has tracked it down to this chip. Any help would be greatly appreciated; Particularly since the people that own the property have sold off the end of the strip to a local farmer who keeps cows there... And the other pilots are a bit too soft to leap the fence and wander through a herd of cattle in the middle of the night just to turn on the lamps... Thanks! JP
