Overview
ą SN75LBC976 9ĆCHANNEL DIFFERENTIAL TRANSCEIVER ą SLLS133D − AUGUST 1992 − REVISED MAY 1995 • Nine Differential Channels for the Data and Control Paths of the Differential Small Computer Systems Interface (SCSI) and Intelligent Peripheral Interface (IPI-2) • Meets or Exceeds the Requirements of ANSI Standard RS-485 and ISO 8482:1987(E) • Packaged in Shrink Small-Outline Package With 25-mil Terminal Pitch • Designed to Operate at 10 Million Transfers Per Second • Low Disabled Supply Current 1.
4 mA Typical • Thermal-Shutdown Protection • Power-Up/Power-Down Glitch Protection • Positive and Negative Output-Current Limiting • Open-Circuit Fail-Safe Receiver Design description The SN75LBC976 is a nine-channel differential transceiver based on the 75LBC176 LinASIC cell.
Use of TI’s LinBiCMOS† process technology allows the power reduction necessary to integrate nine differential transceivers.
On-chip enabling logic makes this device applicable for the data path (eight data bits plus parity) and the control path (nine bits) for both the Small Computer Systems Interface (SCSI) and the Intelligent Peripheral Interface (IPI-2) standard data interfaces.
The SN75LBC976 is packaged in a shrink small-outline package (DL) with improved thermal characteristics using heat-sink terminals.
This package is ideal for low-profile, space-restricted applications such as hard disk drives.
