DS8921AT
DS8921AT is Differential Line Driver and Receiver Pair manufactured by National Semiconductor.
- Part of the DS8921A comparator family.
- Part of the DS8921A comparator family.
Description
The DS8921, 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 DS8921, DS8921A receivers offer an input sensitivity of 200 m V over a ±7V mon mode operating range. Hysteresis is incorporated (typically 70 m V) to improve noise margin for slowly changing input waveforms.
The DS8921, DS8921A drivers are designed to provide unipolar differential drive to twisted pair or parallel wire transmission lines. plementary 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 patible with TTL and CMOS.
