Description
4013 IC Dual
D-Type Flip-Flop
The CD4013B is a monolithic integrated circuit fabricated using complementary MOS (CMOS) technology. It is designed as a dual, independent D-type flip-flop, meaning a single package contains two complete and separate data storage elements. Each flip-flop operates as a fundamental building block in digital electronics, capable of storing a single bit of data. The device is characterized by its high noise immunity and low power consumption, which are typical benefits of the CMOS construction process, making it suitable for a wide range of digital logic applications.
Functionally, each flip-flop within the CD4013B features dedicated data (D), clock (CLK), set (SET), and reset (RESET) inputs, along for complementary outputs (Q and Q-not). The state of the D input is transferred to the Q output upon the application of a clock pulse, specifically on the positive-going edge. The independent Set and Reset inputs, which are active high, allow for the immediate setting or clearing of the flip-flop’s output regardless of the clock signal, providing direct control over the stored data state.
This IC is offered in a variety of package options to accommodate different assembly and space requirements. These include 14-lead ceramic and plastic dual-in-line packages (CDIP, PDIP), as well as small-outline (SOIC) and thin shrink small-outline (TSSOP) packages for surface-mount technology. The
CD4013B
is specified for operation over a broad temperature range, supporting its use in industrial and military environments, and is part of the CD4000 series of logic chips which are known for their wide operating voltage range.
