SP3070E
Every spec below is cited to the manufacturer datasheet. Pick your exact ordering code, compare the closest alternatives, then ask the assistant what it means for your design.
What the SP3070E family does
The SP3070E through SP3078E family serves as ±15kV ESD-protected, 3.3V RS-485/RS-422 transceivers available in full-duplex and half-duplex configurations with speeds up to 16 Mbps. These devices operate from a 3.3V supply, support a common-mode voltage range of -7 to +12V, and feature failsafe receivers for open or shorted lines. The family includes three speed grades: 250 kbps, 500 kbps, and 16 Mbps. Engineers typically use them in industrial control, utility meters, building automation, instrumentation, and point-of-sale systems where robust bus communication is required.
