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

maximum, which makes it ideal for battery powered and pow-

er 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

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.
