DESCRIPTION (CONTINUED)
The receivers can withstand ±15 kV human-body model (HBM) and ±600 V machine model (MM) electrostatic
discharges to the receiver input pins with respect to ground without damage. This provides reliability in cabled
and other connections where potentially damaging noise is always a threat.

SLLS490B–MARCH 2001–REVISED NOVEMBER 2004
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

The receivers also include a (patent pending) failsafe circuit that will provide a high-level output within 600 ns
after loss of the input signal. The most common causes of signal loss are disconnected cables, shorted lines, or
powered-down transmitters. The failsafe circuit prevents noise from being received as valid data under these
fault conditions. This feature may also be used for Wired-Or bus signaling. See
The Active Failsafe Feature of
the SN65LVDS32B
application note.
The intended application and signaling technique of these devices is point-to-point baseband data transmission
over controlled impedance media of approximately 100
. The transmission media may be printed-circuit board
traces, backplanes, or cables. The ultimate rate and distance of data transfer is dependent upon the attenuation
characteristics of the media and the noise coupling to the environment.
The SN65LVDS33, SN65LVDT33, SN65LVDS34 and SN65LVDT34 are characterized for operation from –40°C
to 85°C.
