DS89C386
DS89C386 is Twelve Channel CMOS Differential Line Receiver manufactured by National Semiconductor.
Description
The DS89C386 is a high speed twelve channel CMOS differential receiver that meets the requirements of TIA/ EIA-422-B. The DS89C386 features low power dissipation of 240 m W typical. Each TRI-STATE ® enable, EN, allows the receiver output to be active or in a Hi-impedance off state. Each enable is mon 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 m V over the mon mode range of ± 7V. The receiver outputs (RO) are patible with both TTL and CMOS levels.
