ADVANCE INFORMATION
Refer to the PDF data sheet for device specific package drawings
THVD9491-SEP is a space enhanced, ±70V fault-protected full-duplex RS-422/RS-485 transceiver using a 1.65V to 5.5V logic supply for data and enable logic signals, and a 3V to 5.5V bus side supply. The device has a slew rate select feature that enables the use at two maximum speeds based on the SLR pin setting.
The device features integrated IEC ESD protection, eliminating the need for external system-level protection components. The ±12V input common-mode 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.
THVD9491-SEP device is available in a standard
14-pin SOIC package.
