Working Principles

The TC74LVX373FTELM operates as an octal transparent latch with 3-state outputs. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the corresponding outputs (Q0-Q7). When the output enable (OE) input is low, the outputs are enabled and reflect the state of the inputs. Conversely, when OE is high, the outputs are in a high-impedance state, effectively disconnecting them from the bus.

Detailed Application Field Plans

1. Microcontroller Interfacing: The TC74LVX373FTELM can be used to interface microcontrollers operating at different voltage levels, allowing seamless communication between them.
2. Level Translation: It can be employed in systems where different voltage domains need to communicate, such as in mixed-voltage signal processing or communication interfaces.
3. Bus Sharing: The 3-state outputs make it suitable for bus sharing applications, where multiple devices can share the same bus without interference.
