74LS75 4 Bit D-Latch IC

74LS75 4 Bit D-Latch IC is a reliable and widely used TTL (Transistor-Transistor Logic) quad D-type latch designed for temporary data storage and signal buffering in digital circuits. Featuring four independent transparent latches, the 74LS75 is ideal for applications that require controlled data flow, stable signal retention, and fast switching performance. Built using Low-Power Schottky (LS) technology, this IC delivers high speed with reduced power consumption, making it suitable for educational, industrial, and embedded system applications.

This IC is commonly used in microprocessor-based systems, registers, data buses, and memory interfacing circuits where efficient data latching is required. With separate latch enable inputs and complementary outputs, the 74LS75 offers excellent design flexibility for complex digital logic implementations.

The 74LS75 4 Bit D-Latch IC contains four independent D-type transparent latches controlled by two enable inputs. When the enable input is HIGH, each latch becomes transparent and the output follows the corresponding data input. When the enable input goes LOW, the latch stores and holds the last input value, even if the input changes. Each latch provides both true (Q) and complement (Q̅) outputs. Using low-power Schottky TTL technology, the 74LS75 offers fast switching and stable data storage for digital logic and microprocessor interfacing applications.
