CD4518BPWG4

CD4518BPWG4 is a dual-count JK flip-flop, which is widely used in synchronous logic devices, such as counter, divider, etc.

Application Field

The main application field for CD4518BPWG4 is in the area of synchronous logic circuits, where it can be used as a basic building block for counters, dividers and other circuit elements.

Working Principle

CD4518BPWG4 works under the principle of risetime triggered or data triggered. When a rising logic edge is detected on the clock input pin, the data pattern on the data input pin is latched on to the output. The J and K inputs of the flip-flop are in the disabled state during this operation. When the data pattern is stable on the data input, a one time pulse on the clock input pin causes the data pattern to be latched on to the output.

The output of the flip-flop can be used as the clock input for other adjacent flip-flops to form a counter or divider. Counter and divider circuits can be used for pulse width modulation, clock generation, digital timing and other applications.

CD4518BPWG4 can also be used for shift register applications. In this mode, the data present at the data input pin is shifted from one stage to the next on every rising edge of the clock pin. This allows the serial data to be shifted into a parallel data format.

The CD4518BPWG4 is available in both discrete and integrated circuit configurations. The integrated circuit package has a power supply voltage range of 2.5V to 12V and a maximum clock frequency of 10 MHz.
