Product Overview
The UCC5618DWPTR from Texas Instruments is a 9-channel SCSI (Small Computer System Interface) active terminator designed for high-speed parallel bus termination. It integrates nine 110Ω termination resistors with a precision voltage reference and compensation circuitry to ensure signal integrity in SCSI applications. Housed in a 28-pin SOIC package, this device is ideal for space-constrained designs requiring reliable bus termination.
