  • It can store and retrieve data at high speeds.
  • The latch enable (LE) input controls the storage of data.
  • The output enable (OE) input enables or disables the outputs.
  • Tri-state outputs allow multiple devices to share a common bus.

Advantages and Disadvantages

Advantages: - High-speed data storage and retrieval - Tri-state outputs for bus sharing - TTL logic for compatibility with other ICs - Wide operating temperature range (-40°C to +85°C)

Disadvantages: - Limited number of inputs and outputs (4-bit) - Requires external control signals for proper operation - Not suitable for applications requiring larger data storage capacity

Working Principles

The SN74LS375N operates based on TTL (Transistor-Transistor Logic) technology. It uses flip-flops to store and retrieve data. The latch enable (LE) input controls when the data is stored, while the output enable (OE) input determines whether the outputs are active or in a high-impedance state. The tri-state outputs allow multiple devices to share a common bus without interfering with each other.
