These latches are ideally suited for use as temporary storage 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 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.
The ’LS75 feature complementary Q and Q outputs from a 4-bit latch,and are available in various 16-pin packages.
These circuits are completely compatible with all popular TTL families.All inputs are diode-clamped to minimize transmission-line effects and simplify system design. Series 74LS devices are characterized for operation from 0℃ to 70℃.
