Texas Instruments UCC5672
The UCC5672 Multi-Mode Low Voltage Differential and Single Ended Terminator is both a single ended terminator and a low voltage differential terminator 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 between Single Ended or LVD SCSI Termination, depending on the bus mode.| Part No. | UCC5672 |

DESCRIPTION
If the bus is in High Voltage Differential Mode, the terminator lines transition into a High Impedance state. The UCC5672 is SPI-4, SPI-3, SPI-2, and SCSI-2 compliant. This device is offered in a 28 pin TSSOP package to minimize the footprint. The UCC5672 is also available in a 36 pin MWP package.
