آي سي 7412 (بوابة NAND ثلاثية بثلاثة مداخل مخرج مجمع مفتوح)

These devices contain three independent 3-input NAND gates with open-collector outputs. The open-collector outputs require pull-up resistor to perform correctly. They may be connected to other open-collector outputs to implement active-low wired-OR or active -high wired-AND functions. Open-Collector devices are often used to generate higher VOH levels. The SN5412 and SN54LS12 are characterized for operation over the full military range of -55 degree celcius to 125 degree celcius. The SN7412 and SN74LS12 are characterized for operation from 0 degree celcius to 70 degree celcius. Package Include 4 x 7412 IC
