SN74LS375
4-BIT D LATCH
The SN54/ 74LS375 is a 4-Bit D-Type Latch for use as temporary storage for binary information between processing limits and input /output or indicator units. When the Enable (E) is HIGH, information present at the D input will be transferred to the Q output and, if E is HIGH, the Q output will follow the input. When E goes LOW, the information present at the D input prior to its setup time will be retained at the Q outputs.
