74LS378 IC is a part of the 74XXYY IC series. The 74LS378 is a monolithic, positive edge triggered, registerable flip flop IC that utilizes TTL circuitry to implement D-type Flip-Flop/latching logic. This IC also features a common clock enable instead of a common clear. 74LS378 IC has a wide range of working voltage, a wide range of working conditions, and directly interfaces with CMOS, NMOS, and TTL. The IC 74LS378 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 Flip-Flop/Latch?
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.
