Quad 2-Input NAND Buffers 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.
Pull-Up Resistor Equations
Where:
N
1
(I
OH
)
=
total maximum output high current
for all outputs tied to pull-up resistor
N
2
(I
IH
)
=
total maximum input high current for
all inputs tied to pull-up resistor
N
3
(I
IL
)
=
total maximum input low current for
all inputs tied to pull-up resistor
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
