DESCRIPTION
The UCC5673 Multi-Mode Low Voltage Differential and Single Ended Ter-
minator is both a single ended terminator and a low voltage differential ter-
minator for the transition to the next generation SCSI Parallel Interface
(SPI-3). The low voltage differential is a requirement for the higher speeds
at a reasonable cost and is the only way to have adequate skew budgets.
The automatic mode select/change feature switches the terminator be-
tween Single Ended or LVD Termination, depending on the bus mode. If
the bus is in High Voltage Differential Mode, the terminator lines transition
into a High Impedance state.
The UCC5673 is SPI-3, SPI-2, and SCSI-2 compliant. This device is of-
fered in a 28 pin TSSOP package to minimize the footprint. The UCC5673
is also available in a 36 pin MWP package.
Note: Indicated pinout is for 28 pin TSSOP package.
