Texas Instruments  SN65HVD09DGGR

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 1 mm. 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.

The HVD09 can withstand electrostatic discharges exceeding 12 kV using the human-body model, and 600 V using the machine model on the RS-485 I/O terminals. This provides protection from the noise that can be coupled into external cables. The other terminals of the device can withstand discharges exceeding 4 kV and 400 V respectively.

Each of the nine half-duplex channels of the HVD09 is designed to operate with either RS-422 or RS-485 communication networks.

The SN65HVD09 is characterized for operation over an ambient air temperature range of -40°C to 85°C.
