CD4027BD Dual J-K Master-Slave Flip-Flop 20V 200µA IC DIP-16

Description

CD4027BD Dual J-K
Master-Slave Flip-Flop
20V 200µA IC DIP-16

The CD4027BD is a CMOS logic integrated circuit that contains two independent J-K master-slave flip-flops within a single package. Each flip-flop includes J and K data inputs, a clock input, asynchronous set and reset controls, and complementary Q and Q̅ outputs.

The master-slave configuration ensures reliable state changes synchronized with the clock signal, preventing unwanted transitions. Thanks to CMOS technology, the CD4027BD offers low power consumption, wide operating voltage range, and excellent noise immunity, making it suitable for both low-power battery devices and industrial digital systems.

It is widely used in counters, frequency dividers, memory storage elements, sequencing circuits, and digital control systems, where stable and predictable logic operation is required.

Features:

Dual independent J-K flip-flops.

Master-slave flip-flop architecture.

Asynchronous set and reset inputs.

Complementary Q and Q̅ outputs.

Clock-controlled state switching.

Static operation (data retained without clock).

CMOS logic technology.

High noise immunity.
