DESCRIPTION

KEY FEATURES

■ 3.5pF OUTPUT CAPACITANCE DURING

The LX5204 is a nine-line active terminator

fortheSCSIparallelbus. ThisSCSIstandard

recommends active termination at both

ends of the SCSI bus. The LX5204 has the

added features of hot swappability, fully

complying with the SCSI hot swap speci-

fication.

During disconnect mode, the LX5204 re-

quiresameager60µAofsupplycurrentwhile

offering only 3.5pF of output capacitance.

To enter this low-power mode, the discon-

nect pin can be left open (floating) or driven

high, thereby disconnecting the terminating

resistorsandplacingtheinternallowdropout

regulator into low-power mode. In discon-

nect mode, each termination line presents

a high impedance to the SCSI bus with the

overall effect being to preserve high-signal

integrity and yield subsequent reliable, error-

free communications.

During normal operation, the LX5204

consumes only 600µA of current, which is

DISCONNECT

■ HOT SWAP COMPATIBLE

the lowest enabled supply current of any

terminator available on the market today.

Linfinity's proprietary BiCMOS low dropout

regulator architecture enables this unique

and very efficient operating characteristic.

The LX5204 also offers a precisely

trimmed channel output current specified

to a 5% tolerance. The maximum value

of the output current is trimmed as closely

as possible to the SCSI standard maximum

specification to give the highest possible

noise margin for fast SCSI operation. And

the LX5204 sinks up to 150mA of current,

making it compatible with today's fast

active negation drivers.

The LX5204 is a superior, pin-for-pin

replacement for a variety of industry prod-

ucts such as the UC5603 and UC5613.
