DS89C21 Differential CMOS Line Driver and Receiver Pair
Checkfor Samples: DS89C21
1FEATURES DESCRIPTION
The DS89C21isa differential CMOS line driver and Meets TIA/EIA-422-A (RS-422) and CCITT V.11 receiver pair, designedto meet the requirementsofRecommendation TIA/EIA-422-A (RS-422) electrical characteristics• LOW POWER Design—15 mW Typical interface standard. The DS89C21 provides one driver Guaranteed AC Parameters: and one receiverina minimum footprint. The device offeredinan 8-pin SOIC package.– Maximum Driver Skew 2.0 ns
The CMOS design minimizes the supply currentto6– Maximum Receiver Skew 4.0ns
mA, making the device ideal for use in battery• Extended Temperature Range: −40°Cto poweredor power conscious applications.+85°C
The driver featuresa fast transition time specifiedat• Availablein SOIC Packaging 2.2 ns, anda maximum differential skewof2 ns• Operates over20 Mbps making the driver ideal for use in high speed• Receiver OPEN Input Failsafe Feature applications operating above10 MHz.
The receiver can detect signals as low as 200 mV,
and also incorporates hysteresis for noise rejection.
Skewis specifiedat4ns maximum.
The DS89C21is compatible with TTL and CMOS
levels (DI and RO).
