SN74LS283N Adder IC

- SN74LS383N Binary Full Adder with Fast Carry. A half adder adds 2-bit binary numbers but cannot include a carry bit. In contrast, a Full Adder adds the carry bit along with the two binary numbers, enabling the addition of multi-bit binary numbers by cascading multiple Full Adder circuits.
- Series 74LS
- Number of bits 4
- Number of Elements per Chip 1

Power Filter CW4L2-20A-T

- CW4L2-20A-T EMI Power Filter Single Phase AC 115V/250V 20A 50/60Hz for Laser Machine
- The EMI power line filter works as a low-pass filter that attenuates high-frequency noise in the power line while allowing the desired power frequency (DC or 50/60/400Hz) current to pass through freely. The filter works by diverting the high-frequency noise current away from the device to be protected to the ground.
- Max. Leakage Current Line to Ground: 115VAC 60Hz 0.25mA
- Max. Leakage Current Line to Ground: 250VAC 50Hz 0.45mA

SN74HC86N XOR Gate IC

- Quad 2-Input XOR Logic Gate, 14-Pin PDIP
- Number of Circuits 4
- Number of Inputs 2
- Schmitt Trigger Input No
- Voltage Supply 2V-6V
- SN74HC86N,
- Contains four independent 2-input XOR gates. Each gate performs the Boolean function Y = A βŠ• B in positive logic.
- An XOR gate may serve as a β€œprogrammable inverter” in which one input determines whether to invert the other input, or to simply pass it along with no change. Hence it functions as a inverter (a NOT gate) which may be activated or deactivated by a switch.
