Features, Applications
DS89C386 Twelve Channel CMOS Differential Line Receiver

The is a high speed twelve channel CMOS differential receiver that meets the requirements of TIA/ EIA-422-B. The DS89C386 features low power dissipation 240 mW typical. Each TRI-STATE enable, EN, allows the receiver output to be active in a Hi-impedance off state. Each enable is common to only two receivers for flexibility and multiplexing of receiver outputs. The receiver output (RO) is guaranteed to be High when the inputs are left open and unterminated. The receiver can detect signals as low and including 200 mV over the common mode range 7V. The receiver outputs (RO) are compatible with both TTL and CMOS levels.

Note 1: Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the device should be operated at these limits. The table of "Electrical Characteristics" provides conditions for actual device operation. Note 2: Unless otherwise specified, all voltages are referenced to ground. Note 3: Unless otherwise specified, Min/Max limits apply across the operating temperature range. All typicals are given for VCC = 5V and = 25C. Note 4: Ratings apply to ambient temperature at 25C. Above this temperature derate SSOP (MEA) Package 10.9 mW/C. Note 5: ESD Rating: HEM k, 100 pF) Inputs 2000V Outputs 1000V EIAJ (0, 200 pF) All Pins 350V
