资 源 简 介

These devices contain four independent 2-input posiTIve-NAND buffers with open-collector outputs. They perform the Boolean funcTIons or Y = A + B in posiTIve logic. The open-collector outputs require pullup resistors to perform correctly. These outputs may be connected to other open-collector outputs to implement acTIve-low wired-OR or active-high wired-AND functions. Open-collector devices often are used to generate higher VOH levels. The SN54ALS38B is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS38B is characterized for operation from 0°C to 70°C.
