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
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
