TI SN74S38N

These devices contain four independent 2-input NAND buffer gates with open-collector outputs. The open-collector outputs require pull-up resistors 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 high VoH leveis. The SN5438, SN54LS38, and SN54S38 are characterized for operation over the full temperature range of -55℃ to 125℃. The SN7438, SN74LS38, and SN74S38 are characterized for operation from 0℃ to 70℃
