® RE G5 60 1 REG5601 RE G5 60 1 18-LINE SCSI ACTIVE TERMINATOR FEATURES q COMPLIES WITH SCSI-2 SPECIFICATIONS q INTERNAL 2.9V REGULATOR q ON-CHIP TERMINATION RESISTORS q DISCONNECT ALL TERMINATION RESISTORS WITH A SINGLE LOGIC COMMAND q POWER-DOWN MODE: 150µA max q LINE CAPACITANCE: 10pF typ q CURRENT LIMIT AND THERMAL SHUTDOWN PROTECTION q 28-Lead SOIC and SSOP PACKAGES DESCRIPTION The REG5601 is an 18-line active terminator for SCSI-2 (Small Computer Systems Interface) circuitry. On-chip resistors and 2.9V regulator provide the prescribed 110Ω termination for low power dissipation and high speed data transmission. All line connections can be disconnected from the bus with a single logic control line to reduce standby power consumption. Output lines remain high impedance without power applied. Each line is individually clamped at ground to dissipate negative-going glitches. The 2.9V regulator is current-limited and thermally protected. Regulated output is available for external circuitry. The REG5601 is available in 28-lead SOIC and finepitch SSOP packages and is specified for operation over the 0°C to 70°C temperature range.
