DS8921/DS8921A/DS8921AT  
Differential Line Driver and Receiver Pair  
The DS8921, DS8921A are designed to be compatible with  
TTL and CMOS.  
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.  
Features  
n 12 ns typical propagation delay  
n Output skew - 0.5 ns typical  
n Meet the requirements of EIA Standard RS-422  
n Complementary Driver Outputs  
n High differential or common-mode input voltage ranges  
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.

n
0.2V receiver sensitivity over the input voltage range  
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.  
n Receiver input hysteresis-70 mV typical  
n DS8921AT industrial temperature  
operation: (−40˚C to +85˚C)
