DM74LS75 Quad Latch
DM74LS75
Quad Latch
General Description
These latches are ideally suited for use as temporary stor-
age for binary information between processing units and
input/output or indicator units. Information present at a data
(D) input is transferred to the Q output when the enable 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 Q
outputs
from a 4-bit latch, and are available in 16-pin packages.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

Absolute Maximum Ratings(Note 1)
Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
