The MAX3070E-MAX3079E operate from a single +3.3V supply and feature a 1µA shutdown mode (except the MAX3071E/MAX3074E/MAX3077E). These devices withstand ESD strikes up to ±15kV per Human Body Model, providing added protection to the RS-485 port. The MAX3070E-MAX3079E have a 1/8-unit-load input impedance that allows up to 256 transceivers on the bus. These devices also offer half/full-duplex operation, 16Mbps data rate, slew-rate limiting to reduce EMI and reflections, and receiver/driver enable.
The MAX3070E-MAX3079E are available in the extended and automotive temperature ranges in an industry-standard (75176, 75179, 75180) 8- and 14-pin SO and DIP pinouts. Prices start at $1.75 (1000-up, FOB USA).
