Functional Features

  • Octal transparent latch with 3-state outputs
  • Latch enable (LE) controls the data transfer from inputs to outputs
  • Output enable (OE) allows the outputs to be in a high-impedance state
  • High-speed operation with low power consumption
  • Compatible with TTL (Transistor-Transistor Logic) inputs

Advantages and Disadvantages

Advantages: - High-speed data transfer - Low power consumption - Compatibility with TTL inputs - 3-state outputs for flexible usage

Disadvantages: - Limited output drive capability (15mA at 4.5V) - Restricted operating temperature range (-40°C to +125°C)

Working Principles

The 74HCT373PW-Q100,11 is an octal transparent latch that stores and transfers data. When the latch enable (LE) input is high, the data from the eight data inputs (D0-D7) is transferred to the corresponding outputs (Q0-Q7). The output enable (OE) input controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

  • Data storage and transfer in microcontrollers and microprocessors
  • Address decoding in memory systems
  • Bus interface in digital systems
  • Register storage in various applications
