The MC14027BAL is a Dual J-K Master-Slave Flip-Flop manufactured by Freescale Semiconductor (now NXP). It's a monolithic complementary MOS (CMOS) integrated circuit. Each flip-flop has independent J, K, Set, Reset, and Clock inputs. Changes in output states occur on the positive clock transition. It's suitable for use in shift registers, counters, and control circuits.
Applications:
- Shift registers
- Counters
- Control logic circuits
- Frequency dividers
- Data storage
Features:
- Dual J-K Flip-Flops with Set and Reset
- Fully Static Operation
- Diode Protection on All Inputs
- Supply Voltage Range = 3.0 V to 18 V
- High Noise Immunity: 0.45 VDD (typ.)
- Low Power Consumption
- Standardized, Symmetrical Output Characteristics
Benefits:
- Versatile building block for sequential logic circuits.
- Independent control of each flip-flop enhances design flexibility.
- Low power consumption suitable for battery powered applications.
- High noise immunity ensures reliable operation.
Additional Details:
The MC14027BAL is available in a 16-pin DIP (Dual In-Line Package). The operating temperature range is typically -55°C to +125°C. The flip-flops trigger on the rising edge of the clock signal. A high level on the Set or Reset input forces the corresponding output to a high or low state, respectively, independent of the clock and J-K inputs. The device is used extensively in digital systems requiring sequential logic functions. Detailed datasheets with timing diagrams and applications examples can be found online. The CMOS structure offers high input impedance, which enables the circuit to drive a large number of similar devices.
