MAX3060E/MAX3061E/ 15kV ESD-Protected, Fail-Safe, 20Mbps, MAX3062E Slew-Rate-Limited RS-485/RS-422 Transceivers in a SOT General Description Features The MAX3060E/MAX3061E/MAX3062E high-speed True Fail-Safe Receiver While Maintaining transceivers for RS-485/RS-422 communication contain EIA/TIA-485 Compatibility one driver and one receiver. These devices feature fail- Enhanced Slew-Rate Limiting Facilitates safe circuitry, which guarantees a logic-high receiver Error-Free Data Transmission (MAX3060E and output when the receiver inputs are open or shorted. This MAX3061E) means that the receiver output is a logic high if all 1nA Low-Current Shutdown Mode transmitters on a terminated bus are disabled (high Hot-Swappable for Telecom Applications impedance). These devices also feature hot-swap ESD Protection: 15kV Human Body Model circuitry that eliminates data glitches during hot insertion. Allow Up to 256 Transceivers on the Bus The MAX3060E features slew-rate-limited drivers that Space-Saving 8-Pin SOT23 Package minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free data transmission Ordering Information up to 115kbps. The MAX3061E, also slew-rate limited, transmits up to 500kbps. The MAX3062E driver is not PIN- PART TEMP RANGE slew-rate limited, allowing transmit speeds up to 20Mbps. PACKAGE All transmitter outputs are protected to 15kV using the MAX3060EEKA+T -40C to +85C 8 SOT23-8 Human Body Model. MAX3061EEKA+T -40C to +85C 8 SOT23-8 These transceivers typically draw 910A of supply MAX3062EEKA+T -40C to +85C 8 SOT23-8 current when unloaded, or 790A when fully loaded with the drivers disabled. +Denotes a lead-free package. T = Tape and Reel All devices have a 1/8-unit-load receiver input impedance that allows up to 256 transceivers on the bus. These devices are intended for half-duplex communication.
