Functional Features

The SN74LV374APWE4 is an octal D-type transparent latch with 3-state outputs. It can store and transfer data in digital circuits. The latch is transparent when the latch enable (LE) input is high, allowing the data inputs to be transferred to the outputs. When the LE input is low, the latch holds the last data value. The output enable (OE) input controls the 3-state outputs, enabling or disabling them.

Advantages and Disadvantages

Advantages: - Low-voltage operation allows for compatibility with a wide range of systems - Octal design provides flexibility in digital circuit applications - Transparent latch enables efficient data transfer

Disadvantages: - Limited temperature range (-40°C to 85°C) - TSSOP package may require careful handling during assembly

Working Principles

The SN74LV374APWE4 operates based on the principles of flip-flops. When the latch enable (LE) input is high, the latch becomes transparent, allowing the data inputs (D0-D7) to pass through to the outputs (Q0-Q7). When the LE input is low, the latch holds the last data value, regardless of any changes in the data inputs. The output enable (OE) input controls the 3-state outputs, enabling or disabling them as needed.

Detailed Application Field Plans

The SN74LV374APWE4 is commonly used in various digital circuit applications, including but not limited to: - Microcontrollers - Data storage systems - Communication devices - Industrial automation - Automotive electronics
