  1. OE (Output Enable)
  2. LE (Latch Enable)
  3. D0-D7 (Data Inputs/Outputs)

Group B (Power/Ground Pins)

  1. GND (Ground)
  2. VCC (Supply Voltage)

Functional Features

  • Octal transparent latch with 3-state outputs
  • Non-inverting outputs for easy cascading
  • High-speed operation for efficient data transfer
  • 3-state outputs allow multiple devices to share a common bus
  • Output enable and latch enable control for flexible operation

Advantages and Disadvantages

Advantages

  • High-speed operation enables quick data transfer
  • 3-state outputs facilitate bus sharing among multiple devices
  • Non-inverting outputs simplify cascading of multiple latches
  • Flexible control with output enable and latch enable pins

Disadvantages

  • Limited supply voltage range (2 V to 5.5 V)
  • Propagation delay of 6 ns may not be suitable for ultra-high-speed applications

Working Principles

The SN74AHC373DGVR 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 outputs. The output enable (OE) input controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74AHC373DGVR can be used in various applications that require data storage and transfer. Some potential application fields include:

  1. Microprocessor-based systems
  2. Data communication systems
