TI CD4027BF

The CD4027B is a monolithic integrated circuit chip that contains two identical complementary-symmetry J-K flip-flops. Each flip-flop provides separate J, K, set, reset, and clock input signals, as well as buffered Q and Q (with an overbar) output signals. With these inputs/outputs, compatible operation with the RCA - CD4013B dual D-type flip-flop can be achieved. The CD4027B is suitable for performing control, register, and switching functions. The logic levels at the J and K inputs and internal self-manipulation control the state of each flip-flop; changes in the flip-flop state are synchronized with the positive transition of the clock pulse. The set and reset functions are independent of the clock and are activated when a high-level signal appears at the set or reset input. The CD4027B is available in a 16-pin hermetic dual in-line ceramic package (suffix F3A), a 16-pin dual in-line plastic package (suffix E), a 16-pin small outline package (suffixes M, M96, MT, and NSR), and a 16-pin thin shrink small outline package (suffixes PW and PWR).

• Set/reset latch operation — holds state indefinitely at high or low clock level
