The SN74ACT574NSRE4 is an octal D-type edge-triggered flip-flop with 3-state outputs, designed for operation within a supply voltage range of 4.5 V to 5.5 V. It features TTL-compatible inputs and can accept input voltages up to 5.5 V. The device is optimized for driving capacitive loads and is suitable for applications such as buffer registers, I/O ports, and bidirectional bus drivers. On the positive clock edge, the flip-flops capture the data present at the D inputs and transfer it to the Q outputs. The output-enable (OE) input allows the outputs to be placed in a high-impedance state, facilitating bus organization without additional interface components. The device operates over a temperature range of -40¬8C to 85¬8C and has a maximum propagation delay of 9 ns at 5 V. The SN74ACT574NSRE4 is available in a 20-SOIC package, making it suitable for compact designs. It is important to ensure that unused inputs are tied to VCC or GND for proper operation.
