This document describes the DM7438 and 7438 Quad 2-Input NAND Buffers with Open-Collector Outputs, introduced by Fairchild Semiconductor Corporation in 2000. The device contains four independent gates, each performing the logic NAND function. The open-collector outputs require external pull-up resistors for proper logical operation.
