1 / 10 page  DS89C387 Twelve Channel CMOS Differential Line Driver General Description The DS89C387 is a high speed twelve channel CMOS differ- ential driver that meets the requirements of TIA/EIA-422-B. The DS89C387 features a low I CC specification of 1.5 mA maximum, which makes it ideal for battery powered and power conscious applications. The device replaces three DS34C87s and offers a PC board space savings up to 30%. The twelve channel driver is available in a SSOP package. The device is ideal for wide parallel bus applications. Each TRI-STATE® enable (EN) allows the driver outputs to be active or in a HI-impedance off state. Each enable is com- mon to only two drivers for flexibility and control. The drivers may be disabled to turn off load current and to save power when data is not being transmitted. The driver’s input (DI) is compatible with both TTL and CMOS signal levels.
