UC5601

SCSI Active Terminator

FEATURES

DESCRIPTION

The UC5601 provides precision resistive pull-up to a 2.9V reference for all

18 lines in a Small Computer Systems Interface (SCSI) bus cable. The

SCSI-2 standard recommends active termination at both ends of every ca-

ble segment utilizing single ended drivers and receivers.

•

Complies with SCSI, SCSI-2

Standards

•

10pF Channel Capacitance During

Disconnect

Internal circuit trimming is utilized, first to reduce resistor tolerances to 3%

•

Active Termination for 18 Lines

and then to adjust the regulator’s output voltage to insure termination cur-

Logic Command Disconnects all

Termination Lines

rent accuracy of 3%.

The UC5601 provides a disconnect feature which, upon a logic command,

disconnects all terminating resistors, and turns off the regulator; greatly re-

ducing standby power.

•

Low Supply Current in Disconnect

Mode

Trimmed Regulator for Accurate

Termination Current

Other features include negative clamping on all signal lines, 20mA of active

negation sink current capability, regulator current limiting, and thermal shut-

down protection.

Current Limit and Thermal

Shutdown Protection

This device is offered in low thermal resistance versions of the industry

standard 28 pin wide body SOIC and PLCC, as well as a 24 pin DIL plastic

package.
