ESD Protection

All pins on these devices include class 3 Human Body

Model (HBM) ESD protection structures, but the RS-485

pins (driver outputs and receiver inputs) incorporate

advanced structures allowing them to survive ESD events

in excess of

±15kV HBM. The RS-485 pins are particularly

vulnerable to ESD damage because they typically connect

to an exposed port on the exterior of the finished product.

Simply touching the port pins, or connecting a cable, can

cause an ESD event that might destroy unprotected ICs.

These new ESD structures protect the device whether or

not it is powered up, protect without allowing any latchup

mechanism to activate, and without degrading the RS-485

common mode range of -7V to +12V. This built-in ESD

protection eliminates the need for board level protection

structures (e.g., transient suppression diodes), and the

associated, undesirable capacitive load they present.

Typical Performance Curves VCC = 5V, TA = 25°C; Unless Otherwise Specified
