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.","metaTitle":"MAX221ECAE+ RS-232 Transceiver, 250 kbps","metaDescription":"MAX221ECAE+ is an RS-232 transceiver with full duplex, 250 kbps data rate, 500 mV receiver hysteresis, 4.5V-5.5V supply, -40°C to +85°C.
