Quad Latches
General Descrlption
These latches are ideally suited for use as temporary stor-
age for binary information between processing units and in.
put/output or indicator units. Information present at a data
(D) input is transferred to the 0 input when the enable (G) is
high, and the Q output will follow the data input as long as
the enable remains high. When the enable goes low, the
information (that was present at the data input at the time
the transition occurred) is retained at the Q output until the
enable is permitted to go high.
These latches feature complementary Q and tli outputs
from a 4-bit latch and are available in 16-pin packages.
Features
1: Alternate Military/Aerospace device (5475) is available.
Contact a National Semiconductor Sales Office/Distrib-
utor for specifications.

Note: The "Absolute Maximum Ratings" are those values
beyond which the safety of the device cannot be guaran-

parametric values defined in the "Electn'ca/ Characteristics"
table are not guaranteed at the absolute maximum ratings.
