What the MAX459CQH+ actually is — not a generic amplifier
The MAX459CQH+ from Maxim Integrated is an 8 x 4 video crosspoint switch, not a general-purpose amplifier. It routes any of eight video inputs to any of four outputs — a matrix switch for analog video signals in test equipment, video distribution, and routing applications. The part is listed under the Type "Amplifier" because the switching core uses analog buffer amplifiers on each channel, but the function is signal routing, not gain or filtering.
Package and footprint — the 44-PLCC reality
Housed in a 44-lead PLCC with J-Leads, the MAX459CQH+ measures 16.59 x 16.59 mm body size. This is a legacy surface-mount package still common on video routing boards and ATE fixtures.
Lifecycle — still active, but niche
However, as a specialized video crosspoint switch in a PLCC package, it is not a high-volume commodity part.
