† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
‡ All voltages are with respect to GND. Currents are positive into, negative out of the specified terminal.

The UCC5670 SCSI multimode terminator, comprises both single-ended (SE) and low-voltage differential (LVD) termination and is intended to bridge the transition from single ended to LVD SCSI parallel interface (SPI-2), (SPI-3), and (SPI-4). The low voltage differential signaling configuration is required to meet the higher SCSI speeds and smaller skew budgets. LVD is specified for Ultra2, (Fast-40), Ultra3/Ultra160 (Fast-80), Ultra320 (Fast-160) and meets the requirements for speeds up to Fast-320. The UCC5670 can not be used with High Power Differential (HIPD)(EIA485) devices. When it detects high power differential devices, the terminator lines switch to a high impedance state.

The UCC5670 is offered in a 36-pin MWP package.
