Description

The DS8921N/NOPB, DS8921A are Differential Line Driver and Receiver pairs designed specifically for applications meeting the ST506, ST412 and ESDI Disk Drive Standards. In addition, these devices meet the requirements of the EIA Standard RS-422.The DS8921N/NOPB, DS8921A receivers offer an input sensitivity of 200 mV over a ±7V common mode operating range.Hysteresis is incorporated (typically 70 mV) to improve noise margin for slowly changing input waveforms.The DS8921N/NOPB, DS8921A drivers are 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 0.5 ns (typ.) with propagation delays of 12 ns. DS8921N/NOPB Features • 12 ns typical propagation delay voltage ranges of ±7V• Output skew - 0.5 ns typical• Meet the requirements of EIA Standard RS-422• Complementary Driver Outputs• High differential or common-mode input• ±0.2V receiver sensitivity over the input voltage range• Receiver input hysteresis-70 mV typical
