There were three in the series, the MC1494, MC1495, and MC1496.  The 1496 is still in production and has always been the most popular for ring modulator circuits.

The '94 was an analog multiplier.

The '95 removed the differential current output circuit.

The '96 was bare bones and required a little level shifting.

Yeah, but that was forcing ring modulation on circuits that were never intended for that, so there are going to be quirks and side effects.
