SN74ACT534N Octal D-Type Flip-Flop from Texas Instruments

The SN74ACT534N is a high-performance, octal edge-triggered D-type flip-flop integrated circuit (IC) designed and manufactured by Texas Instruments (TI). This versatile IC is part of the 'ACT' family, known for its advanced CMOS logic that operates at higher speeds while maintaining low power consumption.

The device features eight D-type flip-flops with clear and preset functions, making it ideal for a wide range of applications in data storage, data transferring, and memory register operations. The SN74ACT534N has a wide operating voltage range of 4.5V to 5.5V, which allows for use in various systems without the need for voltage level translation.

Each flip-flop has independent data (D), clock (CLK), set (S̅D̅), and reset (R̅D̅) inputs, and Q and Q̅ outputs. The clear and preset inputs are active low, providing additional control over the flip-flop states. This enables the user to quickly set or reset the flip-flops as needed without waiting for a clock pulse. The edge-triggered clock input ensures that the state of each D input is captured on the rising edge of the clock pulse and then transferred to the corresponding Q output.

The outputs can drive up to 24mA, offering good current sinking capability for interfacing with LEDs, relays, and other output devices. The SN74ACT534N also features 3-state outputs, which enable the IC to be used in bus-oriented applications. By putting the outputs in a high-impedance state, several ICs can share the same output lines without the risk of damaging the circuitry.

The IC is packaged in a 20-pin plastic DIP (Dual In-line Package), making it easy to handle and integrate into various electronic projects. The robust design ensures that the SN74ACT534N can operate over a broad temperature range of -40°C to 85°C, suitable for industrial and automotive applications where reliability is crucial.

Overall, the SN74ACT534N from Texas Instruments is a reliable and versatile choice for designers looking to implement octal D-type flip-flops in their digital systems, offering high-speed operation, low power consumption, and the quality assurance of a leading semiconductor manufacturer.
