I believe the 'C' suffix means the device is frequency compensated internally.
I have never seen a non-C suffix device in use, it's plenty cheap enough to
get that version.  The application would determine suitability.

I used this chip in a light timer once.  It's available from:
    Circuit Specialists Inc.
    P.O. Box 3047
    Scottsdale AZ 85271-3047
    Order number is 1-800-528-1417

They have no minimum order when payment accompanies an order.  The catalog
number is (logically enough) XR2240C.  It's $2.25 each.  There's a $2.00
shipping charge.

I have no connection with them except as a satisfied customer.  They've
always treated me well.
