3 Description
THVD2410 and THVD2450 are ±70-V fault-protected,
half-duplex, RS-422/RS-485 transceivers operating
on a single 3-V to 5.5-V supply. Bus interface pins
are protected against overvoltage conditions during
all modes of operation ensuring robust
communication in rugged industrial environments.
These devices feature integrated IEC ESD protection,
eliminating the need for external system-level
protection components. Extended ±25-V input
common-mode range guarantees reliable data
communication over longer cable run lengths and/or
in the presence of large ground loop voltages.
Enhanced 250-mV receiver hysteresis ensures high
noise rejection. In addition, the receiver fail-safe
feature guarantees a logic high when the inputs are
open or shorted together.
THVD24x0 devices are available in small VSSOP and
VSON packages for space-constrained applications.
These devices are characterized over ambient free-
air temperatures from –40°C to 125°C.
