Working Principles

The SN74LVC373ARGYR operates as an octal transparent latch with 3-state outputs. When the Output Enable (OE) input is high, the latch is transparent, allowing the data inputs (D0-D7) to pass through to the corresponding outputs (Q0-Q7). When the OE input is low, the latch holds the last data input values and the outputs are in a high-impedance state (3-state).

Detailed Application Field Plans

The SN74LVC373ARGYR is commonly used in various applications, including: - Data buses in microprocessors and microcontrollers - Memory address and data latching - Input/output port expansion - General-purpose digital logic circuits
