The LM358 is a low-power dual operational amplifier integrated circuit, originally introduced by National Semiconductor. [1] It uses a single power supply from +3 to +30 volts for V CC (though some variants go higher, such as 36 volts for the LM358B). Input voltage can range from −0.3 volts to V CC.
National Semiconductor Corporation was an American semiconductor manufacturer, which specialized in analog devices and subsystems, formerly headquartered in Santa Clara, California. The company produced power management integrated circuits , display drivers , audio and operational amplifiers , communication interface products and data ...
LM393 differential comparator manufactured by National Semiconductor. The following is a list of LM-series integrated circuits. Many were among the first analog integrated circuits commercially produced since late 1965; [1] some were groundbreaking innovations [opinion]. As of 2007, many are still being used. [2]
Bound copy, from the 1980s, of the MIL-STD-1750A specification document. The 1750A supports 2 16 16-bit words of memory for the core standard. The standard defines an optional memory management unit that allows 2 20 16-bit words of memory using 512 page mapping registers (in the I/O space), defining separate instruction and data spaces, and keyed memory access control.
Similarly numbered devices, with varying levels of compatibility with the original National Semiconductor part, are made by other manufacturers. A UART function that is register-compatible with the 16550 is usually a feature of multifunction I/O cards for IBM PC-compatible computers and may be integrated on the motherboard of other compatible ...
CompactRISC is a family of instruction set architectures from National Semiconductor. The architectures are designed according to reduced instruction set computing principles, and are mainly used in microcontrollers. [1] The subarchitectures of this family are the 16-bit CR16 and CR16C and the 32-bit CRX. [2]
Less common are lower-power versions such as the LM78Mxx series (500 mA) and LM78Lxx series (100 mA) from National Semiconductor. Some devices provide slightly different voltages than usual, such as the LM78L62 (6.2 volts) and LM78L82 (8.2 volts) as well as the STMicroelectronics L78L33ACZ (3.3 volts).
The NS32000, sometimes known as the 32k, is a series of microprocessors produced by National Semiconductor.Design work began around 1980 and it was announced at the International Solid-State Circuits Conference in April 1981.
