DESCRIPTION
The SN65HVD09 is a 9-channel RS-422 / RS-485 transceiver suitable for industrial applications. It offers
improved switching performance, a small package, and high ESD protection. The precise skew limits ensures
that the propagation delay times, not only from channel-to-channel but from device-to-device, are closely
matched for the tight skew budgets associated with high-speed parallel data buses.
