DM74ALS38A Quadruple 2-Input NAND Buffer with Open-Collector Outputs
September 1986
Revised February 2000
DM74ALS38A
Quadruple 2-Input NAND Buffer
with Open-Collector Outputs
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.
