MAX22507E/MAX22508E

50Mbps Full-Duplex RS-485/RS-422

Transceivers with High EFT Immunity

General Description

Benefits and Features

The MAX22507E/MAX22508E ESD-protected RS-485/

RS-422 full-duplex transceivers are optimized for high-

speed communication up to 50Mbps. These transceivers

feature integrated hot-swap protection and a fail-safe re-

ceiver, ensuring a logic-high on the receiver output when

input signals are shorted or open for longer than 10μs

(typ). Additionally, a large receiver hysteresis improves

noise rejection and signal integrity.

● High-Speed Operation Over Long Distances

• Up to 50Mbps Data Rate

• High Receiver Sensitivity

• Wide Receiver Bandwidth

• Symmetrical Receiver Thresholds

● Integrated Protection Increases Robustness

• -15V to +15V Common Mode Range

• ±15kV ESD Protection (Human Body Model)

• ±7kV IEC 61000-4-2 Air-Gap ESD Protection

• ±6kV IEC 61000-4-2 Contact Discharge ESD

Protection

The MAX22507E/MAX22508E are designed to operate in

harsh industrial environments and are optimized for robust

communication in environments with high levels of electro-

magnetic interference (EMI).

• Withstands Over ±4kV EFT

• Driver Outputs are Short-Circuit Protected

The MAX22507E is available in a 10-pin μMAX package

and the MAX22508E is available in an 8-pin SOIC pack-

age. μMAX is the Maxim-trademarked equivalent to the in-

dustry-standard MSOP package. Both transceivers oper-

ate over the -40°C to +125°C temperature range.

● Flexibility for Many Different Applications

• 3V to 5.5V Supply Range

• Low 5μA (max) Shutdown Current (MAX22507E)

• Allows up to 200 Transceivers on the Bus

• Available in a 10-pin μMAX Package (MAX22507E)

and 8-pin SOIC Package (MAX22508E)

Applications

● Motion Control

• -40°C to +125°C Operating Temperature Range

● Encoder Interfaces

● Field Bus Networks

● Industrial Control Systems

● Backplane Busses
