74LS74 D-Type Positive Edge Triggered Flip-Flop IC – Datasheet

74LS74 IC is a member of the 74XXYY IC series. The 74LS70 IC has a wide range of working voltage, a wide range of working conditions, and directly interfaces with CMOS, NMOS, and TTL. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers. 74LS74 flip-flop IC utilizes the Schottky TTL circuitry to produce high-speed D-type flip-flops. Each flip-flop has individual clear and set inputs, and also complementary Q and Q`(bar) outputs.

What is a D-Type Flip-Flop?

A D-type flip-flop is a clocked flip-flop which has two stable states. A D-type flip-flop 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 delay flip-flop.
