QUADRUPLE 2-INPUT POSITIVE-NAND BUFFERS WITH OPEN-COLLECTOR OUTPUTS

These devices SN54ALS38B SN74ALS38B contain four independent 2-input positive-NAND Buffers with open-collector outputs. They perform the Boolean functions Y = A B 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 55C to 125C. The SN74ALS38B is characterized for operation from 0C to 70C. By Texas Instruments
