  • High-speed operation allows for efficient data transfer
  • Output enable (OE) pin controls the output state, enabling bus-oriented applications
  • Latch enable (LE) pin controls the storage and retrieval of data

Advantages and Disadvantages

Advantages: - High-speed operation enables quick data transfer - 3-state outputs facilitate bus-oriented applications - Non-inverting outputs simplify integration into digital systems

Disadvantages: - Limited output current capability compared to some other ICs - Requires external clock pulse (CP) and latch enable (LE) signals for proper operation

Working Principles

The SN74ABT373NSR 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). The output enable (OE) input controls whether the outputs are in a high-impedance state or actively driving the output lines.
