• Compact Package: The TSSOP20 package allows for efficient board space utilization.

The TC74VCX373FK features eight D-type transparent latches. When the Latch Enable (LE) input is HIGH, the Q outputs follow the data (D) inputs. When LE is LOW, the Q outputs are latched and retain the last data present before the transition. The device also incorporates an Output Enable (OE) input, which, when HIGH, forces the Q outputs to a high-impedance state. This feature is useful for implementing memory systems or bused architectures.

The device is available in a TSSOP20 package and is RoHS compliant, ensuring environmental friendliness.
