Functional Features

The SN74LS375DR is an octal D-type transparent latch with 3-state outputs. It allows data to be stored and retrieved in a high-speed manner. The latch is transparent when the latch enable (LE) input is high, allowing the data inputs to pass through to the outputs. When the LE input is low, the latch holds the last data value. The output enable (OE) input controls whether the outputs are active or in a high-impedance state.

Advantages and Disadvantages

Advantages: - High-speed operation - Low-power consumption - Compact SOIC package - 3-state outputs for bus-oriented applications

Disadvantages: - Limited voltage range (4.75V to 5.25V) - Propagation delay time may affect timing-sensitive applications

Working Principles

The SN74LS375DR operates based on the principles of digital logic. When the latch enable (LE) input is high, the latch is transparent, allowing the data inputs to propagate to the outputs. 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 whether the outputs are active or in a high-impedance state. This IC is designed to operate within a specific voltage range and temperature range.

Detailed Application Field Plans

The SN74LS375DR can be used in various applications, including but not limited to: - Data storage and retrieval systems - Address decoding circuits - Bus-oriented systems - Digital communication systems - Microcontroller-based projects
