© 1999 Fairchild Semiconductor Corporation DS009465 www.fairchildsemi.com April 1988 Revised November 1999 74F38 Quad Two-Input NAND Buffer (Open Collector) 74F38 Quad Two-Input NAND Buffer (Open Collector) General Description This device contains four independent gates, each of which performs the logic NAND function. The open-collector out- puts require external pull-up resistors for proper logical operation. Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
