Texas Instruments (DS8921ATM/NOPB) Differential Line Driver / Receiver

Product Overview The DS8921ATM/NOPB is a differential Line Driver and Receiver Pair designed specifically for applications meeting the ST506, ST412 and ESDI disk drive standards. In addition, this device meets the requirements of the EIA standard RS-422. The DS8921x receiver offers an input sensitivity of 200mV over a ±7V common mode operating range. Hysteresis is incorporated (typically 70mV) to improve noise margin for slowly changing input waveforms. The DS8921x driver is designed to provide unipolar differential drive to twisted-pair or parallel wire transmission lines. Complementary outputs are logically ANDed and provide an output skew of 0.5ns (typical) with propagation delays of 12ns. The device is designed to be compatible with TTL and CMOS. 12ns Typical propagation delay 0.5ns Typical output skew 70mV Typical receiver hysteresis Meets the requirements of EIA standard RS-422 Complementary driver outputs Green product and no Sb/Br Applications Industrial Product Information Device Type: Line Driver / Receiver IC Interface Type: RS422 No. of Drivers: 2Drivers No. of Receivers: 2Receivers Supply Voltage Min: 4.5V Supply Voltage Max: 5.5V Driver Case Style: SOIC No. of Pins: 8Pins Operating Temperature Min: -40°C Operating Temperature Max: 85°C Product Range: - Automotive Qualification Standard: - MSL: MSL 1 - Unlimited
