54F/74F38 Quad Two-Input NAND Buffer (Open Collector)

December 1994

54F/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 out­puts require external pull-up resistors for proper logical op­eration.
