DS2121A LVD SCSI Terminator is a Low Voltage Differential (LVD) terminator produced by Dalsemi. It supports Ultra2, Ultra3, and Ultra 160 LVD-only SCSI, and can provide LVD termination for 9 signal line pairs. The tolerance on SE and LVD termination resistance is not more than 5%. Its power-down capacitance is only 3 pF. It has onboard thermal shutdown circuitry and is SCSI bus hot plug compatible. It can be widely used in various electronic devices.

The DS2120A Ultra3 LVD SCSI Terminator is a Low Voltage Differential (LVD) terminator. If the device is connected in an LVD-only bus, the DS2120A will use LVD termination. If any single-ended (SE) or high-voltage differential (HVD) devices are connected to the bus, the DS2120A will isolate itself from the SCSI bus. This is accomplished automatically inside the part by sensing the voltage on the SCSI bus DIFFSENS line. For the LVD termination, the DS2120A integrates two current sources with nine precision resistor strings. Three DS2120A terminators are needed for a wide SCSI bus.

DS2120 is a SCSI bus terminator produced by Maxim Semiconductor. It supports Ultra3, Ultra160, Ultra320, Ultra2 SCSI standards, and LVD protocol. It supports automatic selection of LVD termination, zero temperature coefficient termination resistors, low power-down capacitance, built-in mode change filter/delay, and on-board thermal shutdown circuitry.

The DS2119M is a fully compliant LVD/SE SCSI terminator with SCSI SPI-2, SPI-3, SPI-4, Ultra160, and Ultra320 support. It provides multimode low-voltage differential/single-ended (LVD/SE) termination for nine signal-line pairs and has automatic LVD or SE termination selection. The terminator is SCSI-bus hot-plug compatible and features onboard thermal-shutdown circuitry. It fully supports actively negated SE SCSI signals. Three DS2119M terminators are needed for a wide SCSI bus.

The DS2118M is a Ultra2 LVD/SE SCSI terminator from Dalsemi. It supports both LVD and SE modes and can be used on LVD and SE buses. It has auto-selection of LVD or SE termination and has a 5% tolerance on SE and LVD termination resistance. Its power down capacitance is low and it is hot plug compatible.
