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 pre-
scribed 110
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 imped-
ance 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 fine-
pitch SSOP packages and is specified for operation
over the 0 C to 70 C temperature range.
