3 Description

THVD24xxV are ±70V fault-protected, half and full-duplex RS-422/RS-485 transceivers using a 1.65V to 5.5V supply for logic signal interface, 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. Extended ±25V 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.
