Functional Features

  • Octal transparent D-type latches with 3-state outputs
  • Latches store data when clock signal is high
  • Data inputs are transferred to the outputs when the latch enable (LE) input is low
  • Outputs can be disabled by setting the output enable (OE) input high
  • Suitable for bus-oriented applications

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data transfer - Wide operating voltage range provides flexibility in various systems - 3-state outputs enable easy integration into bus-oriented applications - Output drive capability of 15 LSTTL loads ensures compatibility with different devices

Disadvantages: - Limited output current may restrict use in certain high-power applications - Propagation delay time and output transition time may affect overall system performance in time-critical applications

Working Principles

The SN74HC373DWRG4 operates as an octal transparent latch. When the clock input (CLK) is high, the latch stores the data present at the data inputs (D0-D7). The stored data is then transferred to the corresponding data outputs (Q0-Q7) when the latch enable (LE) input is low. The output enable (OE) input can be used to disable the outputs, allowing multiple devices to share a common bus.

Detailed Application Field Plans

The SN74HC373DWRG4 can be used in various applications, including but not limited to: - Microprocessor-based systems - Data storage and transfer systems - Address decoding circuits - Bus-oriented architectures - Memory modules - Industrial control systems

Detailed and Complete Alternative Models

Some alternative models to the SN74HC373DWRG4 include: - 74HC373: Similar octal transparent latch with 3-state outputs, but in a different package (DIP) - CD74HC373: Octal transparent latch with 3-state outputs from a different manufacturer (Texas Instruments) - MC74HC373: Octal transparent latch with 3-state outputs from another manufacturer (Motorola)

These alternative models offer similar functionality and can be used as substitutes depending on specific requirements.
