Functional Features

• Octal transparent latch with 3-state outputs
• Latch enable (LE) input controls the latching of data on the inputs
• Output enable (OE) input enables/disables the outputs
• High-speed CMOS technology allows for fast operation
• Low voltage operation makes it suitable for battery-powered devices

Advantages and Disadvantages

Advantages: - Compact size and integration of multiple latches in a single chip - Low power consumption due to low voltage operation - Fast propagation delay time for quick data processing - 3-state outputs provide flexibility in connecting multiple devices

Disadvantages: - Limited supply voltage range (2.0V to 3.6V) - Temperature limitations (-40°C to +85°C) - Surface mount package may require specialized equipment for soldering

Working Principles

The 74LCX373MSA is an octal transparent latch that can store data on its inputs and control the output states. The latch enable (LE) input determines when the data on the inputs is latched and stored. The output enable (OE) input enables or disables the outputs. When the OE input is high, the outputs are in a high-impedance state, allowing other devices to drive the bus. When the OE input is low, the outputs reflect the data stored in the latch.

Detailed Application Field Plans

The 74LCX373MSA is commonly used in various digital logic applications, including:

1. Microprocessor systems
2. Data storage systems
3. Communication equipment
4. Industrial automation
5. Consumer electronics
