Rated for 250kbps data rate with 500mV of receiver hysteresis, it handles industrial serial communication over the -40°C to 85°C temperature range without needing a separate charge-pump capacitor network — the internal charge pump generates the RS232 voltage levels from the single supply. ## Full-duplex at 250 kbps — what it means for the serial link The 250kbps data rate supports standard RS232 communication. Full-duplex operation means the driver and receiver can run simultaneously — no half-duplex turnaround delay, so the link sustains bidirectional throughput without protocol overhead for direction switching. The 500mV receiver hysteresis filters out noise on longer cable runs, reducing the chance of false start bits on a noisy factory floor. ## Supply and temperature: single-rail convenience with industrial margin Operates from a single supply rail, so it drops into existing 5V logic systems without a separate RS232 supply converter. The -40°C to 85°C operating range qualifies it for outdoor telecom cabinets, unheated factory bays, and engine-adjacent enclosures where commercial-grade parts would drift out of spec. ## Lifecycle and sourcing: active production, no LTB risk ROHS3 compliant, which covers the latest EU exemption updates for lead-free assembly.","metaTitle":"MAX221ECAE+T RS232 Transceiver, 250kbps, 16-SSOP","metaDescription":"MAX221ECAE+T RS232 transceiver, full duplex, 250kbps data rate, 4.5V-5.5V supply, industrial temp -40°C to 85°C, 16-SSOP.
