Texas Instruments SN74LVTH574 3.3-V ABT Octal Edge-Triggered D-Type Flip-Flops With 3-State Outputs SN74LVTH574PWR

The SN74LVTH574 is a 3.3-V ABT octal edge-triggered D-type flip-flop featuring 3-state outputs. It is designed for low-voltage operation while supporting mixed-mode signal environments, allowing for 5-V input and output voltages. The device includes eight flip-flops that capture data on the rising edge of the clock input, with a buffered output-enable (OE) input to control the output state, enabling high-impedance operation when necessary. This flip-flop supports unregulated battery operation down to 2.7 V and features active bus-hold circuitry to maintain valid logic levels on unused inputs, eliminating the need for external pull-up or pull-down resistors. The device is fully specified for hot-insertion applications, with Ioff and power-up 3-state support to prevent backflow current during power transitions. It is available in various packages, including TSSOP, and operates over a temperature range of -40°C to 85°C. The SN74LVTH574 is suitable for applications requiring reliable data storage and transfer in low-voltage systems.
