Quad 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.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
