Overview
The SN74LS75N is a 4-bit bistable latch integrated circuit produced by Texas Instruments. It is part of the 74LS series, known for its low power Schottky logic. This device is designed for temporary storage of binary information between processing units and input/output or indicator units. The latch operates in a transparent mode, where the output follows the input as long as the enable signal is high. When the enable signal goes low, the information present at the data input is retained at the output until the enable is set high again.
