  • Latch enable (LE) and output enable (OE) control signals
  • High-speed operation suitable for bus-oriented applications
  • Low-voltage operation for power efficiency
  • Eight latches in a single package for compact design

Advantages and Disadvantages

Advantages: - Low-voltage operation allows for power-efficient designs - High-speed operation enables fast data transfer - 3-state outputs facilitate bus-oriented applications - Compact package with eight latches saves board space

Disadvantages: - Limited operating temperature range (-40°C to 85°C) - Requires external clock pulse (CP) and latch enable (LE) signals

Working Principles

The SN74LV573ATNSR operates as an octal transparent D-type latch with 3-state outputs. When the latch enable (LE) signal is high, the input data is transferred to the outputs based on the clock pulse (CP) signal. The output enable (OE) signal controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74LV573ATNSR can be used in various applications, including but not limited to: - Data storage and transfer in microcontrollers and microprocessors - Address and data bus interfacing in embedded systems - Parallel-to-serial and serial-to-parallel conversion - Memory address decoding and selection - General-purpose digital logic circuits
