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.
