74F38 Quad Two-Input NAND Buffer (Open Collector)
April 1988
Revised September 2000
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:

Note 2:
Absolute maximum ratings are values beyond which the device
may be damaged or have its useful life impaired. Functional operation
under these conditions is not implied.
Note 3:
Either voltage limit or current limit is sufficient to protect inputs.
