DS8921ATM/NOPB Description

Short technical summary and product information.

The DS8921ATM/NOPB from Texas Instruments is a differential line driver and receiver pair designed for applications meeting ST506, ST412, and ESDI disk drive standards, as well as EIA RS-422.

 

This transceiver offers a typical propagation delay of 12 ns and an output skew of 0.5 ns. The receiver sensitivity is ±0.2 V over a ±7 V common-mode operating range, with typical input hysteresis of 70 mV to enhance noise margin. The drivers provide unipolar differential drive to transmission lines.

 

Designed for compatibility with TTL and CMOS logic, the DS8921ATM/NOPB operates within a voltage range of 4.5V to 5.5V. It is housed in an 8-SOIC package suitable for surface mounting.

 

Key electrical characteristics include a maximum signaling rate of 10 Mbps and a maximum supply current of 35 mA. The device supports fault protection up to ±12 V and can operate in industrial temperature ranges from -40°C to 85°C.
