74LS375 Quad 4-Bit D-Type Bi-Stable Latch IC | Datasheet

The 74LS375 IC is a part of the 74XXYY IC series. The 74LS375 IC 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. 74LS375 IC has a wide range of working voltage, a wide range of working conditions, and directly interfaces with CMOS, NMOS, and TTL. The IC 74LS375 is smaller in size and it has a much faster speed which makes it reliable in every kind of device.

What is a D-Type Latch/Flip-Flop?

A D-type Latch/flip-flop is best described as a clocked latch, that has two stable states. A D-type latch operates with a delay in input by one clock cycle. Thus, by cascading many D-type flip-flops delay circuits can be created, which are used in many applications such as in digital television systems. A D-type flip-flop is also known as a D flip-flop or a delay flip-flop.
