Additional Details

The TC74LCX374FT(EL,K) features eight D-type flip-flops with a common clock (CK) and output enable (OE) input. When OE is low, the data at the D inputs is transferred to the Q outputs on the positive-going edge of the clock. When OE is high, the Q outputs are in the high-impedance state. The device operates within a supply voltage range of 2.0 V to 3.6 V and is characterized for operation from -40°C to +85°C. It is available in a TSSOP20 package, making it suitable for surface mount applications.
