3 Description 1 The DS8921, DS8921A, and DS8921AT devices are • 12-ns Typical Propagation Delay differential line driver and receiver pairs designed • Output Skew: 0.5 ns Typical specifically for applications meeting the ST506, • Meets the Requirements of EIA Standard RS-422 ST412, and ESDI disk drive standards. In addition, • Complementary Driver Outputs these devices meet the requirements of the EIA standard RS-422. • High Differential or Common-Mode Input Voltage Ranges of ±7 V The DS8921x receivers offer an input sensitivity of 200 mV over a ±7 V common mode operating range. • ±0.2 V Receiver Sensitivity Over the Input Voltage Hysteresis is incorporated (typically 70 mV) to Range improve noise margin for slowly changing input • Receiver Input Hysteresis: 70 mV Typical waveforms. • DS8921AT Industrial Temperature Operation: The DS8921x drivers are designed to provide (−40°C to +85°C) unipolar differential drive to twisted-pair or parallel wire transmission lines. Complementary outputs are 2 Applications logically ANDed and provide an output skew of 0.5 ns • Differential Line Driver and Receiver (typical) with propagation delays of 12 ns. for: – ST506 Disk Drive Standard The DS8921x devices are designed to be compatible – ST412 Disk Drive Standard with TTL and CMOS. – ESDI Disk Drive Standard Device
