Working Principles

The 74VHCT373ATTR is a transparent latch with 3-state outputs. It allows data to be stored and transferred between different components of a digital system. The latch is controlled by the latch enable (LE) input, which determines whether the inputs are latched or transparently passed to the outputs. When the LE input is high, the latch is enabled, and the data at the inputs is stored. When the LE input is low, the latch is disabled, and the outputs are in a high-impedance state.

Detailed Application Field Plans

The 74VHCT373ATTR IC finds applications in various digital systems, including but not limited to: - Microcontrollers - Data storage devices - Communication systems - Industrial automation - Automotive electronics
