SN74AHCT74N by Texas Instruments
The SN74AHCT74N is a high-performance, dual positive-edge-triggered D-type flip-flop integrated circuit designed and manufactured by Texas Instruments. This device is part of the 'AHCT' family of logic devices, which are known for their high-speed operation and compatibility with TTL (Transistor-Transistor Logic) levels.
Each flip-flop has individual clear and set inputs, along with a common clock input, making the SN74AHCT74N versatile and suitable for a wide range of applications in digital systems. The device features a 2-V to 5.5-V VCC operation, ensuring that it can be powered by a variety of sources and is compatible with most 5V systems.
The outputs can drive up to 8 LSTTL loads, providing sufficient current for interfacing with other standard logic families. The SN74AHCT74N is characterized for operation from -40°C to 85°C, making it reliable for use in industrial environments where temperature extremes may be encountered.
The flip-flops in SN74AHCT74N are edge-triggered, meaning that the state of the flip-flop changes on the rising edge of the clock signal. This provides precise control and timing of state changes, which is crucial for synchronous digital circuits. The clear and set inputs are asynchronous, allowing for immediate resetting or setting of the flip-flop independent of the clock signal.
Packaged in a 14-pin PDIP (Plastic Dual-In-line Package), the SN74AHCT74N is designed for easy insertion into a variety of socket or printed circuit board (PCB) configurations. Its industry-standard pinout makes it interchangeable with other similar devices, allowing for flexibility in design and upgrades to existing systems.
Texas Instruments ensures that the SN74AHCT74N meets stringent quality and performance standards, providing designers with a reliable component for constructing digital logic circuits, such as counters, shift registers, and state machines. The availability of detailed datasheets, application notes, and design resources from Texas Instruments supports engineers in the effective implementation of the SN74AHCT74N in their projects.
