MAX3078E Overview
Description
The MAX3070E–MAX3079E 3.3V, ±15kV ESD-protected, RS-485/RS-422 transceivers feature one driver and one receiver. These devices include fail-safe circuitry, guaranteeing a logic-high receiver output when receiver inputs are open or shorted.
Key Features
- one driver and one receiver
- These devices include fail-safe circuitry, guaranteeing a logic-high receiver output when receiver inputs are open or shorted
- The receiver outputs a logic-high if all transmitters on a terminated bus are disabled (high impedance)
- The devices include a hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion
- The MAX3073E/ MAX3074E/MAX3075E also feature slew-rate-limited drivers but allow transmit speeds up to 500kbps
- The MAX3076E/MAX3077E/MAX3078E driver slew rates are not limited, making transmit speeds up to 16Mbps possible
- The MAX3079E slew rate is pin-selectable for 250kbps, 500kbps, and 16Mbps
- The MAX3079E is selectable for half-duplex or full-duplex operation
- It also features independently programmable receiver and transmitter output phase through separate pins
- The MAX3070E–MAX3079E transceivers draw 800μA of supply current when unloaded, or when fully loaded with the drivers disabled
