3 Description

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

RS-422/RS-485 transceivers using a 1.65 V to

5.5 V supply for logic signal interface, and a 3 V to

5.5 V 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 systemlevel

protection components. Extended ±25-V

input common-mode range makes reliable data

communication over longer cable run lengths and/or

in the presence of large ground loop voltages.

Enhanced 250-mV 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.
