Disadvantages

  • Limited output current may restrict use in certain applications
  • Requires external control signals for proper operation

Working Principles

The M74HCT373B1R is an octal D-type transparent latch with 3-state outputs. It stores and transfers data using latch enable (LE) and output enable (OE) control signals. When LE is high, the latch is transparent, allowing the input data to pass through to the outputs. When LE is low, the latch holds the last input data. The OE signal controls the output state, enabling or disabling the outputs.

Detailed Application Field Plans

The M74HCT373B1R can be used in various applications that require data storage and transfer, such as:

  1. Microprocessor-based systems
  2. Data communication equipment
  3. Industrial control systems
  4. Instrumentation and measurement devices
  5. Automotive electronics
