Functional Features

  • The SN74ABT373DWR is an octal transparent latch with 3-state outputs.
  • It allows data to be latched and stored when the latch enable (LE) input is high.
  • The output enable (OE) input controls the 3-state outputs, allowing them to be in a high-impedance state when disabled.
  • The non-inverting outputs provide a true representation of the stored data.

Advantages and Disadvantages

Advantages: - High-speed operation suitable for bus-oriented applications - Non-inverting outputs provide accurate data representation - Power-up 3-state feature ensures controlled output during power-up - Latch-up performance exceeds industry standards

Disadvantages: - Limited supply voltage range (4.5V to 5.5V) - Output current limitations may restrict certain applications

Working Principles

The SN74ABT373DWR operates by using the latch enable (LE) input to control the storage of data. When LE is high, the inputs (D0-D7) are latched and stored in the internal flip-flops. The stored data can then be accessed through the outputs (Q0-Q7). The output enable (OE) input determines whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74ABT373DWR is commonly used in various applications, including:

  1. Data storage and retrieval systems
  2. Bus-oriented architectures
  3. Memory interfacing
  4. Address decoding
  5. Data buffering
