This part belongs in indoor, climate-controlled equipment — office automation, point-of-sale terminals, instrumentation racks. Not suited for outdoor telecom cabinets or unheated enclosures without additional thermal management.
24-pin EDIP (0.600 inch, 15.24 mm pitch), through-hole mount. The module footprint is larger than a surface-mount SOIC or TSSOP, so board area is a consideration. The through-hole package simplifies hand-assembly and rework — a plus for prototype runs or field repair.
The part is ROHS3 compliant.
