1 / 8 page DS8921/DS8921A/DS8921AT Differential Line Driver and Receiver Pair General Description The DS8921, DS8921A are Differential Line Driver and Re- ceiver pairs designed specifically for applications meeting the ST506, ST412 and ESDI Disk Drive Standards. In addi- tion, these devices meet the requirements of the EIA Stan- dard RS-422. The DS8921, DS8921A receivers offer an input sensitivity of 200 mV over a ±7V common mode operating range. Hyster- esis is incorporated (typically 70 mV) to improve noise mar- gin for slowly changing input waveforms. The DS8921, DS8921A drivers are designed to provide uni- polar differential drive to twisted pair or parallel wire trans- mission lines. Complementary outputs are logically ANDed and provide an output skew of 0.5 ns (typ.) with propagation delays of 12 ns. The DS8921, DS8921A are designed to be compatible with TTL and CMOS.
