Texas Instruments DS8921 Differential Line Drivers and Receiver Pair DS8921N

The DS8921 is a differential line driver and receiver pair designed for applications that comply with ST506, ST412, and ESDI disk drive standards. It features complementary driver outputs and is compatible with TTL and CMOS logic levels. The device offers a typical propagation delay of 12 ns and an output skew of 0.5 ns. The receivers have a high input sensitivity of 200 mV over a common-mode voltage range of ¬±7 V, with a typical input hysteresis of 70 mV to enhance noise margin. The DS8921 is available in an 8-pin SOIC package with a body size of 4.90 mm x 3.91 mm, and it operates within a temperature range of -40¬8C to +85¬8C for the industrial version (DS8921AT). This product is suitable for applications requiring reliable differential signaling over twisted-pair or parallel wire transmission lines.
