Functional Features

• The DM74ALS373SJ is an octal transparent latch with tri-state outputs.
• It can store and transfer 8 bits of data.
• The tri-state outputs allow multiple devices to be connected together, enabling bus sharing.

Advantages

• High-speed operation allows for efficient data transfer.
• Low-power consumption helps in reducing energy usage.
• Tri-state outputs enable bus sharing and reduce the number of required pins.

Disadvantages

• Limited number of bits (8) may not be suitable for applications requiring larger data storage.
• The PDIP package may not be ideal for space-constrained designs.

Working Principles

• When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the outputs (Q0-Q7).
• When the output enable (OE) input is low, the outputs are active and reflect the data inputs.
• When OE is high, the outputs are in a high-impedance state, allowing other devices to drive the bus.

Detailed Application Field Plans

The DM74ALS373SJ can be used in various applications, including: 1. Microprocessor systems 2. Data storage and retrieval systems 3. Communication equipment 4. Industrial control systems 5. Automotive electronics
