UCC5638FQPTR TI SCSI Terminator | 48-LQFP (7x7) | 9-Line, 110 Ohm

Product Overview

The UCC5638FQPTR from Texas Instruments is a 9-line SCSI (Small Computer System Interface) active terminator designed for high-performance data bus termination. Housed in a compact 48-pin LQFP (7x7 mm) package, it provides precise impedance matching and signal integrity for SCSI parallel interfaces. This device integrates nine termination channels with 110-ohm output impedance, compliant with SCSI-1, SCSI-2, and Ultra SCSI standards. It operates over a wide supply voltage range of 4.0V to 5.5V and features low output capacitance (typically 6 pF) to minimize signal distortion. The UCC5638FQPTR is ideal for applications requiring reliable bus termination in high-speed digital systems.
