Hermetic video mux-amp for high-reliability signal chains
The 5962-9451202MRA is a MAX455 CMOS video multiplexer-amplifier — a single-chip 2:1 mux followed by a 50 MHz unity-gain-stable amplifier, packaged in a 20-lead ceramic CDIP (0.300" body width) for through-hole mounting. The 300 V/µs slew rate and 50 MHz -3 dB bandwidth suit it for composite video switching, RGB routing, or any analog signal path that needs a buffered mux with minimal group-delay variation.
The 20-CDIP ceramic package (0.300" wide, 7.62 mm lead spacing) is the hermetic, high-reliability variant — the same die as the plastic DIP but sealed in a ceramic body with a lid seal that passes fine-leak testing. The RoHS non-compliant marking is expected for a mil-screened CDIP — the lead finish is typically tin-lead solder dip, exempt under Annex III of the RoHS directive for high-reliability applications.
Sourcing and provenance check for the CDIP variant
Because this is a ceramic-package part destined for mil/aero or long-life industrial equipment, the date-code and marking consistency matter more than for a commodity plastic part. The MAX455 die is a known Maxim (now Analog Devices) design; the 5962-9451202MRA is the standard military drawing (SMD) number that maps to the full-temp-range screened version. When sourcing through independent distribution, the laser-etch font on the ceramic lid and the package's hermeticity (no porosity, no re-marking) are the first checks.
