SN65HVD09DGG

RS-485接口IC 9Ch RS485/RS422 Xcvr

DESCRIPON

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. Patented thermal enhancements are used in the thin shrink, small-outline package TSSOP, allowing operation over the industrial temperature range. The TSSOP package offers very small board area requirements while reducing the package height to 1mm. This provides more board area and allows component mounting to both sides of the printed circuit boards for low-profile, space-restricted applications such as small form-factor hard disk drives.
