74LS75 4-Bit Bi-Stable Latch contains 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 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 . 74LS75 IC can be soldered directly to the circuit board or can be mounted on a 14 pin IC base. Operating supply voltages to the IC can vary between 4.5V to 5V and to a maximum of 5.5V and the input logic levels to the device in ‘0’ (LOW) state is max. 0.7V and for ‘1’ (HIGH) state is min 2V.

Features of 74LS75 4-Bit Bi-Stable Latch:
