Discontinued National Semi LM devices available

6 August 2014 News Analogue, Mixed Signal, LSI

Rochester Electronics has reintroduced the popular National Semiconductor LM family of linear products as part of its Extension of Life products and solutions.

National Semiconductor established itself as a linear leader with the introduction of the first monolithic voltage regulator in 1967 with the LM100. Rochester Electronics has Texas Instruments’ (which bought out National Semiconductor) approval to continue recreating the linear LM Series to match original form, fit and function.

The devices listed below have since reached end-of-life, but are still used actively among military and defence applications. Rochester Electronics has the capability to continue the authorised manufacture of these devices in the traditional package and temperature range options, as well as custom packages and temperature ranges if required. It also has substantial inventories of finished devices and die/wafers of many other LM products not listed below.

* LM108, 208, 308 – Operational amplifiers.

* LM105, 205, 305 – Voltage regulator.

* LMx06 – Voltage comparators.

* LM112, 212, 312 – Operational amplifiers.

* LM118, 218, 318 – Operational amplifiers.

* LMx31 – Precision voltage to frequency converters.

* LM161, 261, 361 – Differential comparators.

* LM723 – Adjustable positive single-output standard regulator.

* LM741 – Operational amplifier.

* LM759 – Operational amplifier.
