3 Description

THVD24xxV-EP are ±70V fault-protected, half and

full-duplex RS-422/RS-485 transceivers using a 1.65V

to 5.5V logic supply for data and enable logic signals,

and a 3V to 5.5V bus side supply. These devices have

slew rate select feature that enables them to be used

at two maximum speeds based on the SLR pin setting

These devices feature integrated IEC ESD protection,

eliminating the need for external system-level

protection components. The ±12V input commonmode

range makes reliable data communication over

longer cable run lengths and/or in the presence

of large ground loop voltages. Enhanced 250mV

receiver hysteresis provides high noise rejection. In

addition, the receiver fail-safe feature makes sure of

a logic high when the inputs are open or shorted

together.

THVD24xxV-EP half-duplex devices are available

in small VSON package for space-constrained

applications. The devices are available in standard

14-SOIC package.
