TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information The DS8921 is a differential line driver and receiver pair in a single package, designed for applications for the ST506, ST412, and ESDI Disk Drive Standards. The DS8921 is compatible to EIA RS-422 signaling standards, supporting 200-mV input sensitivity across a ±7-V common mode operating range. This transceiver is intended for driving differential signal across long transmission lines and translating received differential signals into their CMOS/TTL single-ended equivalence. The DS8921 transmits and reproduces received data in communications links where ground reference difference, or noisy environment are common. 9.2 Typical Application Figure 11 shows a typical implementation of the DS8921x device in a ST506 and ST412 disk drive application. The differential outputs of the driver are connected to a twisted-pair transmission line, carrying data from the driver to the differential receiver at the other end of the cable. A differential termination resistor should be connected across the input pins of the receiver. Figure 11.
