Dallas Semiconductor

Dallas Semiconductor, acquired by Maxim Integrated in 2002 for $2.5 billion,then acquired by Analog Devices in 2021, was a company that designed and manufactured analog, digital, and mixed-signal semiconductors (integrated circuits, or ICs). Its specialties included communications products (including T/E and Ethernet products), microcontrollers, battery management, thermal sensing and thermal management, non-volatile random-access memory, microprocessor supervisors, delay lines, silicon oscillators, digital potentiometers, real-time clocks, temperature-compensated crystal oscillators (TCXOs), iButton, and 1-Wire products.

DS2120E+T&R Products

The DS2120E Ultra3 LVD SCSI terminator is a low-voltage differential (LVD) terminator. If the device is connected in an LVD-only bus, the DS2120E uses LVD termination. If any single-ended (SE) or high-voltage differential (HVD) devices are connected to the bus, the DS2120E disconnects from the bus. This is accomplished inside the part automatically by sensing the voltage on the SCSI bus DIFFSENS line.
For the LVD termination, the DS2120E integrates two current sources with nine precision resistor strings. Three DS2120E terminators are needed for a wide SCSI bus.
