NE/SA/SE556/NE556-1 is a dual timer circuit, which is a dual integrated timer circuit of 555. It has high precision and stability and is used to generate accurate time delays or oscillation. The two timers operate independently of each other, sharing only VCC and GND. The clock can be provided by an external resistor and capacitor for each timing function.

555 timer is a low-cost programmable timer that has one-shot, astable and multivibrator functions. It is easy to use and widely used in various measurement and control circuits.

The LM193/A/293/A/393/A/2903 is a low power dual voltage comparator from Philips Semiconductors. It features a very low input biasing current and offset voltage, and can be directly interfaced with TTL and CMOS logic.

LM258/358/A/2904 is a pair of independent, high gain, internally frequency-compensated operational amplifiers specifically designed to operate from a single power supply over a wide range of voltages. Operation from dual power supplies is also possible, and the low power supply current drain is independent of the magnitude of the power supply voltage.

The LM124/SA534/LM2902 series consists of four independent, high-gain, internally frequency-compensated operational amplifiers designed specifically to operate from a single power supply over a wide range of voltages. The unique features include an input common-mode voltage range that includes ground and an output voltage that can swing to ground, even though operated from only a single power supply voltage. The unity gain crossover frequency and the input bias current are temperature-compensated.

This is a product specification for the LM124/224/324/324A/SA534/LM2902 series of low power quad op amps. These products have high gain, internal frequency compensation, and are specifically designed for single supply operation over a wide range of voltages.
