UCC5638FQPTR Description

Short technical summary and product information.

The UCC5638FQPTR from Texas Instruments is a multimode SCSI terminator designed for LVD SCSI Parallel Interface (SPI-2, SPI-3, SPI-4) applications. It automatically senses the bus type and switches termination between single-ended (SE) and low-voltage differential (LVD) modes, or to a high-impedance state if a HVD SCSI device is detected. This device meets SCSI-1, SCSI-2, Ultra2 (SPI-2 LVD SCSI), Ultra3, Ultra160 (SPI-3), and Ultra320 (SPI-4) standards.

 

Key features include auto-selection for SE or LVD termination, differential failsafe biasing for signal integrity, and operation over a voltage range of 2.7V to 5.25V. The UCC5638FQPTR is specified for an operating temperature range of 0°C to 70°C. It is supplied in a 48-pin LQFP package, suitable for surface mounting.

 

This multimode terminator integrates all necessary functions for terminating and auto-detecting modes, providing a smooth transition into LVD SCSI bus architectures. Its design ensures trimmed single-ended and differential impedances for maximum effectiveness.
