What is SN75LVDM976DLRG4 used for?
The SN75LVDM976DLRG4 is designed for high-speed SCSI storage subsystems requiring reliable LVD signaling at data rates compliant with SCSI-3 (X3.277) and SCSI-2 standards. It suits server backplane designs, RAID controller cards, and industrial storage arrays where 9 bidirectional transceiver channels per device reduce component count. Engineers also use it in test and measurement equipment where differential bus integrity across long cable assemblies is critical.

Frequently Asked Questions
What electrical standards does SN75LVDM976DLRG4 support, and what does that mean for system compatibility?
SN75LVDM976DLRG4 complies with X3.277, SCSI-2, and SCSI-3 standards, enabling interoperability across legacy and modern SCSI devices. The device supports both single-ended and low-voltage differential (LVD) operation, meaning a single IC handles mixed SCSI environments without external level-shifting logic, saving PCB space and bill-of-materials cost in storage subsystems.
How many channels does SN75LVDM976DLRG4 provide, and what input structure does it use?
The device integrates 9 bidirectional transceiver channels, each with a differential Schmitt trigger input for improved noise rejection. The high-level input current maximum is 50 µA, and the 56-pin SOIC package keeps parasitic inductance low, making it suitable for SCSI buses operating at speeds up to Ultra3 SCSI data rates.
When would a designer choose SN75LVDM976DLRG4 over a single-ended SCSI buffer in a RAID controller design?
In RAID controllers where cable lengths exceed 1.5 m or data rates approach Ultra2/Ultra3 SCSI thresholds, LVD signaling offered by SN75LVDM976DLRG4 maintains signal integrity far better than single-ended alternatives. Its 9 integrated channels reduce the chip count by consolidating transceivers that would otherwise require multiple single-channel devices, cutting board area and power consumption in multi-drive enclosures.
