Features

* n n n n n 12 ns typical propagation delay Output skew - 0.5 ns typical Meet the requirements of EIA Standard RS-422 Complementary Driver Outputs High differential or common-mode input voltage ranges of ± 7V n ± 0.2V receiver sensitivity over the input voltage range n Receiver input hysteresis-70 mV

Applications

* meeting the ST506, ST412 and ESDI Disk Drive Standards.
In addition, these devices meet the requirements of the EIA Standard RS-422. The DS8921, DS8921A receivers offer an input sensitivity of 200 mV over a ± 7V common mode operating range.
Hysteresis is incorporated (typically 70 mV) to improve noi
