Temperature range and operating environment
Rated from -40°C to 85°C, the MAX221ECAE+ fits industrial enclosures, outdoor telecom cabinets, and unventilated control panels. No derating worry for ambient heat near motor drives or power supplies — the industrial temperature grade covers the typical factory floor.
Package and footprint
Housed in a 16-SSOP (0.209", 5.30 mm width) surface-mount package. The narrow-body SSOP saves board area compared to a wide SOIC. Supplier device package is 16-SSOP; footprint matches standard SSOP-16 land pattern.
Compliance and lifecycle
ROHS3 compliant, so no substance-restriction paperwork for EU-bound equipment. The + suffix in the order code indicates lead-free / RoHS-compliant finish; the base MAX221ECAE (without +) is the tin-lead version still found in some old BOMs.
