Additional Details:

The TC74ACT374FT is characterized for operation over a wide temperature range. The 3-state outputs allow the device to be connected directly to bus lines, enabling multiple devices to share the same bus. When the output enable (OE) input is high, the outputs are in a high-impedance state, effectively disconnecting the device from the bus. When OE is low, the outputs are enabled, and the data stored in the flip-flops is presented on the outputs. The device is positive-edge triggered, meaning that data is loaded into the flip-flops on the rising edge of the clock signal. The direct clear (CLR) input allows the flip-flops to be reset asynchronously, regardless of the clock signal. The TC74ACT374FT is typically available in a TSSOP package, suitable for surface mount assembly. Designers should consult the datasheet for specific timing parameters, voltage levels, and power dissipation figures to ensure proper system operation. The ACT family offers improved noise immunity and drive capability compared to standard CMOS logic.
