Additional Details
The 74HC373PV-E features a transparent mode when the latch enable (G) is high. In this mode, the Q outputs follow the data input (D) values. When G goes low, the data present at the D inputs is latched. The output enable (OC) input controls the three-state outputs; when OC is low, the outputs are enabled, and when OC is high, the outputs are in the high-impedance state. The part is typically available in surface mount packages, making it suitable for modern electronic designs.
