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

Detailed and Complete Alternative Models

Some alternative models that offer similar functionality to the 74VHCT373ATTR IC include: - 74HC373: High-speed CMOS octal D-type latch with 3-state outputs - SN74LS373: Octal transparent latch with 3-state outputs - CD74ACT373: Octal transparent latch with 3-state outputs
