描述 Description

CD4027BMS is a single monolithic chip integrated circuit containing two identical complementary-symmetry J-K master slave flip-flops. Each flip-flop has provisions for individual J, K, Set Reset, and Clock input signals. Buffered Q and Q signals are provided as outputs. This input-output arrangement provides for compatible operation with the Intersil CD4013B dual D type flip-flop.

The CD4027BMS is useful in performing control, register, and toggle functions. Logic levels present at the J and K inputs along with internal self-steering control the state of each flip-flop; changes in the flip-flop state are synchronous with the positive-going transition of the clock pulse. Set and reset functions are independent of the clock and are initiated when a high level signal is present at either the Set or Reset input.

The CD4027BMS is supplied in these 16-lead outline packages:

?? Braze Seal DIP H4T

?? Frit Seal DIP H1E

?? Ceramic Flatpack H6W
