Additional Details

The TC74HC374AF-TP2 is an octal D-type flip-flop. The device contains eight flip-flops with a common clock (CK) input and a common output enable (OE) input. Data at the D inputs are transferred to the Q outputs on the positive-going edge of the clock pulse. The three-state output buffers are controlled by the output enable (OE) input. When OE is low, the buffers are enabled. When OE is high, the buffers are in the high-impedance state. The device is supplied in a SOP20 package. The -TP2 suffix typically indicates specific packaging or tape and reel options for automated assembly.
